Math Tips

(Pictures are not mine)

Well, let me tell you, we all have this love-hate relationship with this subject, right? The worst part is that when you don't know what the heck is going on, so, as a girl who studied maths (2 Volumes/textbooks) on her own during the year she was homeschooled, here are some tips and tricks that I did to get an A+ in my math finals!

Get your syllabus together

In the beginning I had no damn idea what was going on and it was just confusing. I had to do the first thing I did was taken my index/table of contents and mark the chapters which i knew very well and the ones I had no clue about. And then i arranged them with the marking scheme, like which one carries the most marks etc etc and study accordingly.

Complete lessons/chapters that you already know

When you finish off the things you already know then that's gonna give you the confidence you need even if you know only 1-2 chapters, learn it throughout and make sure that you'll get the answer no matter how twisted the sum is. If you're doubtful about the whole textbook like any normal person.... Start with the easy ones. (I know there are literally really no "easy" chapters, spare me)

Harder chapters need hard work

Most chapters like Trigonometry proofs, Geometry proofs, Algebra, Graphs, Mensuration and Calculus etc need more than minimum effort but here's a trick, what is the common thing in this? Yes, they're all formulae and theorem based which goes to my next point. These chapters are completely based on how much you've understood your basics.

Formulae and theorem cheatsheets

Make a list of all formulae and the theorem used in the book, write them chapter wise and no printouts or digital notes. Take a paper and write it down, no excuses. It helps you while you're practicing, revising and in the last minute review, it helped me damn much. Remember, maths is a sport. The basic formulae must come to you like reflexes.

YouTube is your best friend.

For every single chapter, go and watch the basics and how a sum is done step by step. A recommendation for this is Organic Chemistry Tutor who literally is one of the reasons i passed. He has videos from basic geometry, trigonometry, statistics to calculus. Search for your own YouTubers and be clear with concepts.

Math is fully memorization

Memorize formulae and theorems with the back of your hand, you should be able to recall them within seconds. Be thorough.

Memorize basic math values (if calculator isn't allowed)

Do this if you have a majority of chapters like Statistics, Mensuration, Profit/loss calculation etc, where large numbers are concerned. Memorize the first 10 square, cube, decimal and multiplication values. It may be dry but there are literally songs available for these things, I'm serious, i learnt the first 10 cube roots by listening to Senorita xD Search for rhymes and they'll definitely be many!!

Work it out!!!!!!

Can't stress this enough, atleast 30-40 mins is the minimum for maths. I'm serious, work out each sum, don't ever think it's a waste, you'll see the results. Practice makes perfect. Work out every single sum, from examples to exercise ones cause let's be honest, our examiners love to take problems from every nook and cranny of the book.

Whiteboard method

So, I made this up and it actually works, if you have a whiteboard or anything else, once you completed a chapter, take a random page and whatever sums you have on those two pages, you need to complete within a given time limit. It helps you to identify your weak points and where the hell you're losing both time and effort and not to mention that it gives you confidence boost up.

Hope this helps :))

[raven-at-the-writing-desk]

i have a silly question and was wondering what your thoughts might be. iirc ace's best subject is listed as magic analysis (elective) class. and in the beginning of book 7 when sebek is screaming in the cafeteria, ace mentions that he shares that elective class with sebek. what /is/ Magic Analysis Class?? like. what's the field of study?? my brain can't really think up a concept, are they analyzing the construction of magic spells?? their rate of success?? is it like a magic statistics class?? i have no idea but i was curious if you had any idea

We have some clarification as to what Magic Analysis (or Enigmics, as it is sometimes called in EN) is in Ace's third birthday card (the Broomquet series). It's not yet out in the official localization, but I can summarize the related information for you ^^ The class appears to be very math focused, with some sample questions being “Express the strength of this fire magic as an equation", “Express phenomenon A using this magical formula,”, and “Derive the power of magic B using this equation" (fan translation provided by mysteryshoptls). Ace cites Magic Analysis as being a class he enjoys because all he needs to remember are formulas, and he still gets partial credit for some problems.

So in short, it's definitely math-based but not statistics. Magic Analysis seems closer to algebra, trigonometry, calculus, or general mathematical logic. Maybe a physical science.

Strategies to Enhance Problem-Solving Skills for JEE

The Joint Entrance Examination (JEE) is one of the toughest exams in India, requiring not just knowledge but also advanced problem-solving skills. Excelling in JEE demands a sharp mind and an ability to think critically under pressure. Whether it's solving complex math problems or understanding tricky concepts in physics, developing effective problem-solving techniques is key to success. Here are some strategies to enhance your problem-solving skills for JEE:

JEE Training in Coimbatore

1. Master the Basics

Before attempting advanced questions, ensure that you have a strong understanding of fundamental concepts. Skipping the basics may lead to confusion when tackling higher-level problems. Spend time reviewing core topics in mathematics, physics, and chemistry. Clear concepts help in quicker identification of the right approach for solving problems.

2. Practice Regularly

Consistent practice is essential for improving problem-solving abilities. Regularly solving a wide range of problems exposes you to different types of questions and helps you understand various solving techniques. Use practice books and mock tests to refine your skills. The more problems you solve, the better you’ll become at identifying patterns and applying formulas quickly.

3. Break Down Problems

For complex problems, break them down into smaller, manageable parts. This step-by-step approach can simplify the problem and make it easier to solve. Identify what the question is asking, list out known information, and work through the steps logically. Developing this habit will increase your speed and accuracy on exam day.

JEE Coaching in Coimbatore

4. Understand Multiple Approaches

In JEE, there’s often more than one way to solve a problem. Familiarize yourself with different methods for solving the same type of question. This versatility can be a game-changer during the exam, as some approaches may be quicker or more effective for specific problems. For instance, you may solve a physics question using both the formula-based and graphical method, depending on which approach fits the situation best.

5. Time Management

Efficient problem-solving isn't just about finding the right answer; it's about finding it quickly. Develop your ability to assess how much time to spend on a problem. If you get stuck, don’t dwell on it—move to the next question and return to it later if time permits. Practicing with time-bound mock tests helps simulate exam conditions, improving your ability to make decisions under pressure.

6. Learn from Mistakes

Reviewing your mistakes is one of the best ways to improve problem-solving skills. After completing mock tests or practice problems, thoroughly analyze any mistakes you made. Identify where you went wrong and make sure you understand how to correct it. Learning from errors helps you avoid similar pitfalls in the future.

JEE Training in Coimbatore

7. Focus on Conceptual Understanding

JEE problems often test your conceptual understanding rather than just rote learning. Focus on understanding the 'why' behind each concept. This deeper comprehension allows you to apply the concepts in various scenarios, enhancing your problem-solving ability. For example, understanding the principles of mechanics in physics can help you solve a range of motion-related problems efficiently.

8. Strengthen Mental Math Skills

Developing mental math skills can significantly cut down the time you spend on calculations during the JEE. Practice solving mathematical problems without relying on calculators or paper. This skill is especially helpful in sections where quick numerical solutions are required, like trigonometry, algebra, and calculus.

9. Stay Calm Under Pressure

Stress can hinder your problem-solving ability. Use relaxation methods, such as deep breathing, to maintain calmness during the exam. A clear, focused mind is essential for effectively solving challenging questions. During practice sessions, simulate exam-like conditions to train your mind to stay composed under pressure.

JEE Coaching in Coimbatore

10. Seek Guidance When Needed

If you’re struggling with a particular topic or problem type, don’t hesitate to seek help. Whether it’s from your teachers, friends, or online resources, getting clarification on difficult topics can clear mental blocks. Collaborative learning and discussing different approaches with peers can also sharpen your problem-solving skills.

Conclusion

Developing strong problem-solving skills is essential for cracking JEE, but it doesn’t happen overnight. By mastering the basics, practicing consistently, and adopting the right strategies, you can gradually enhance your problem-solving abilities.

Top Strategies for Tackling GCSE OCR Math: A Comprehensive Study Guide

When it comes to GCSE OCR Maths, success doesn’t solely depend on natural ability. A well-thought-out strategy can make all the difference. Whether you are confident with numbers or find maths challenging, a structured approach will help you feel more prepared and perform at your best.

At School of Coding, we have years of experience helping students succeed in their GCSE Maths exams. Here’s our comprehensive guide to preparing for OCR Maths, focusing on key strategies that can set you up for success. If you want to dive deeper, we also offer online and offline tutoring through our website SOC Learning.

1. Familiarise Yourself with the OCR Exam Format

The first step to successful revision is understanding what you’re up against. The GCSE OCR Maths exam consists of three papers: one non-calculator paper and two calculator papers. Each section is designed to test your knowledge across a variety of topics, from algebra and geometry to probability and trigonometry. Familiarising yourself with the layout of the exam will give you a clearer idea of what to expect and allow you to plan your revision accordingly.

2. Set a Realistic Revision Schedule

Effective revision starts with a solid plan. Organise your time in advance, allowing more study hours for areas you find tricky while maintaining a balance across all topics. A helpful tip is to break up your study sessions into short bursts. Many students find the Pomodoro Technique useful — studying for 25 minutes, followed by a 5-minute break. This approach can help keep you focused without getting overwhelmed.

3. Prioritise Understanding Over Memorisation

It can be tempting to rely on memorising formulas or procedures, but a deeper understanding of the material will serve you better in the long run. Spend time ensuring you comprehend the underlying concepts behind key topics like algebra, ratios, or geometry. Once you understand the "why" behind a solution, tackling similar questions becomes much easier, even if they’re phrased differently.

4. Practice, Practice, Practice!

Practice is the cornerstone of any good maths revision strategy. The more you expose yourself to different types of questions, the better equipped you’ll be to handle the variety that OCR exams can throw at you. Focus on practising past papers, which are widely available online, and aim to complete them under timed conditions to simulate the exam experience.

5. Tackle Your Weak Points First

It’s natural to avoid topics you find difficult, but tackling them head-on will make a significant difference to your overall performance. Make a list of the areas you struggle with the most — whether that’s quadratic equations or complex fractions — and dedicate extra time to improving them. If needed, consider reaching out for help from a teacher, or sign up for additional tutoring at School of Coding.

6. Take Advantage of Online Tools and Resources

The internet is packed with free resources that can enhance your revision. Websites like BBC Bitesize, Khan Academy, and Corbett Maths offer tutorials, videos, and practice questions covering every topic in the GCSE OCR Maths syllabus. In addition, at School of Coding, we offer tailored tutoring sessions and classes to help GCSE students master difficult concepts.

7. Regularly Review Your Progress

Don’t just move on from a topic after you’ve covered it once. Regular review is critical to cement your knowledge. Make it a habit to revisit notes, past papers, and difficult questions regularly. The more you refresh your memory, the better you’ll retain the information, and the more confident you’ll feel when the exam day approaches.

8. Learn to Manage Exam Time

Time management is crucial in maths exams. Once you're familiar with the question styles, practise completing past papers within the given time limits. Knowing how long to spend on each question will prevent you from rushing or leaving answers incomplete.

9. Stay Positive and Don’t Stress

Maths can be daunting, but try to stay positive throughout your revision journey. Stress can make things seem harder than they actually are. Take breaks, get enough rest, and maintain a healthy balance between studying and downtime. When you approach revision with a calm and determined mindset, you’ll notice a big improvement in your ability to focus and retain information.

At School of Coding, we believe that anyone can achieve great results with the right support. Whether you need help with specific topics or would like guidance with your overall study strategy, our GCSE Maths tutors are here to help you through every step of your revision journey.

What are the Standard Angles of Trigonometric Table? 

The Trigonometric Table is essentially a tabular compilation of trigonometric values and ratio for various conventional angles such as 0°, 30°, 45°, 60°, and 90°, often with extra angles such as 180°, 270°, and 360° included. Due to the existence of patterns within trigonometric ratios and even between angles, it is simple to forecast the values of the trigonometry table and to use the table as a reference to compute trigonometric values for many other angles. The sine function, cosine function, tan function, cot function, sec function, and cosec function are trigonometric functions.

The trigonometric table is helpful in a variety of situations. It is required for navigating, research, and architecture. This table was widely utilized in the pre-digital age, even before pocket calculators were available. The table also aided in the creation of the earliest mechanical computing machines. The Fast Fourier Transform (FFT) algorithms are another notable application of trigonometric tables.

Standard Angles of Trigonometric Table

The values of trigonometric ratios for the angles 0°, 30°, 45°, 60°, and 90° are widely utilized to answer trigonometry issues. These values are related to measuring the lengths and angles of a right-angle triangle. Hence, the standard angles in trigonometry are 0°, 30°, 45°, 60°, and 90°. Following are the trigonometry angle tables (show the figure).

The trigonometric table in its simplest sense refers to the collection of values of trigonometric functions of various standard angles including 0°, 30°, 45°, 60°, 90°, along with other angles such as 180°, 270°, and 360°. These angles are all included in the table. This makes it easier to determine and arrive at the values of the trigonometric ratios in a trigonometric table, also, the table can be used as a referral illustration to compute trigonometric values for various other angles, due to the patterns that are seen within the trigonometric ratios and those between angles.

The table as one might note, consists of trigonometric ratios – sine, cosine, tangent, cosecant, secant, and cotangent. The short forms of these are very popular – sin, cos, tan, cosec, sec, and cot, respectively. Always, memorize the values of the trigonometric ratios of the standard angles.

Always remember these points in the trigonometric table:

In a trigonometric table, the trigonometric values for complementary angles, such as 30° and 60° are measured by applying complementary formulas for various trigonometric ratios.

The value for some ratios in a table is ∞ “not defined”. The reason is that while computing values, the denominator shows a “0”, which implies that the trigonometric value cannot be defined, and is as good to be the equivalent of infinity.

Please notice the sign change in the values at places under 180°, and 270°, for values of some trig ratios in a trigonometric table. This happens because there is a change in the quadrant.

Trigonometric values

As explained, if trigonometry deals with the relationship between the sides of a triangle (right-angled triangle) and its angles, then the trigonometric value refers to the values of different ratios, sine, cosine, tangent, secant, cotangent, and cosecant, all in the trigonometric table. All the trigonometric ratios are in relation with the sides of a right-angle triangle. The trigonometric values are derived applying these the ratios. Refer to the following steps to create trigonometric values:

Steps to Create Values for Trigonometry Table

Step 1: 

Make a table with the top row showing the angles such as 0°, 30°, 45°, 60°, and 90°, and the first column listing the trigonometric functions such as sin, cos, tan, cosec, sec, cot.  

Step 2: Determine the value of sin 

To find the sin values, divide 0, 1, 2, 3, 4 by 4 under the root, in that order.

Step 3: Determine the value of cos 

The cos-value is the inverse of the sin angle. To find the value of cos, divide by 4 in the opposite order as sin.

Step 4: Determine the value of tan 

Tan is defined as sin divided by cos. Tan equals sin/cos. Divide the value of sin at 0° by the value of cos at 0° to get the value of tan at 0°.

Step 5: Determine the value of cot 

The reciprocal of tan is the value of cot. Divide 1 by the value of tan at 0° to get the value of cot at 0°. As a result, the value will be as follows: cot 0° = 1/0 = Unlimited or Not Defined  

Step 6: Determine the value of cosec 

The reciprocal of sin at 0° is the value of cosec at 0°. 

Step 7: Determine the value of sec 

Any common values of cos may be used to calculate sec. The value of sec on 0° is the inverse of the value of cos on 0°.

While we learn trigonometric values of the trigonometry tables, it will also be interesting to take note of the application areas of the table. On a broader note, the trigonometric table is used in:

Science, technology, engineering, navigation, science and engineering. Before the advent of the digital era, the trigonometric table was very effective. In the course of time, the table helped in the conceptualization of mechanical computing devices. Trigonometric tables are also used in the Fast Fourier Transform (FFT) algorithms.

Important Tricks to Remember Trigonometry Table

Knowing the trigonometry table can help you answer trigonometry problems and remembering the trigonometry table for normal angles ranging from 0° to 90° is simple. Knowing the trigonometric formulae makes remembering the trigonometry table much easier. The trigonometry formulae are required for the Trigonometry ratios table.

The angle values of trigonometric functions, cotangent, secant, and cosecant are computed by applying these standard angle values of sine, cosecant, and tangent. All the higher angle values of trigonometric functions such as 120°, and 360°, are easier to compute, through the standard angle values in a trigonometric values table.

If you still can’t remember the values of Trigonometry tables, consider Tutoroot personalised sessions. Our Maths online Tuition session will help you clearly understand the table along with tricks to memorize.

So I'm in finals season...so here's the og team during finals!

Wow I haven't made a post like this in a hot minute

First off, Black Canary would be the one to make sure that there were regular homework nights

Because, y'know, she's the only adult that actually cares

She always supervises/helps. One time Red Tornado was told to supervise

It did not go well

Kaldur tries *so hard* to be helpful

He's the team mom, right? So you'd think he'd be super helpful

WRONG

My man went to military school and then dropped out of magic school to become a superhero. Probably only learned stuff from an Atlantean pov.

Some stuff? He's super good at. Like I can see him being really good at English since it's he's bilingual

But you show this man a trigonometry question and he will have a mental breakdown

That's where Wally and Dick come in

Are actually super helpful

Sort of

They're prodigies, so they know everything (especially math and science stuff). But (this may be an unpopular opinion) Wally is a much better tutor than Dick

Sure Wally will absolutely get distracted and eat all your snacks, but I feel like eventually Dick would just get frustrated and want to do your work for you

Which is exactly why Dinah supervises

Of course he gets better once he becomes Nightwing, but Robin Dick Grayson is a little shit and isn't always the most cool-headed guy. Not a great team player

Wally, however? He's gonna be hyping you up when you get frustrated, making jokes, can break things down to a basic level. He's great I miss him

During actual finals though...you *know* that these two chucklefucks are procrastination kings.

With Wally it's understandable, he could write an essay or finish a bunch of chemistry revision in the blink of an eye

But Dick...between school, superheroing, etc. Nobody knows when this guy is finishing his assignments. During cramming sessions he'll do like, five minutes of actual work? Then go play games with Wally (if Dinah and Kaldur aren't paying attention). And yet he's still getting 90s, boi how-

We already know M'gann is making all he bomb-ass study snacks

I feel like she would learn how to make coffee just for finals season to help her friends. Actually becomes really good at it. Good for you M'gann.

Isn't the *best* student academic wise, but she does alright. She does genuinely try to focus during study sessions, although I also feel like she'd get distracted by making sure everyone was comfortable ("do you want more snacks?" "I have a blanket you could borrow!" "Does anyone want music?", etc.).

Is definitely that girl that makes her notes all pretty and Aesthetic™ though, so everyone wants to borrow her notes come finals season. Also makes flash cards for everyone

Conner...I'm not gonna lie, he's the worst person to study with

Kinda like Wally and Dick: already knows everything, doesn't take notes, is probably off doing something else (in this case, probably practicing or watching static)

But unlike the Dumbass Duo, he genuinely seems to just...not care. And especially season 1 Conner can be kind of a prick about it

Dinah: Conner, come back here, you need to revise

Conner: *lists off the formula by heart without even looking at her*

Although, to be fair, if you're stuck on something and need to know the answer, it's a whole lot faster to ask him then to look it up/find it in your notes

And he likes helping M'gann in the kitchen (makes terrible coffee though)

So he's got some perks

Now, Artemis

We already know she slaps in English class (she's a literature major in college), and we know she does her assignments in a timely manner (or at least better than Wally)

But also...I kinda feel like this girl is *a mess* in finals season

She's got that Asian Parenting Mom™ yelling in the back of her brain that she's never prepared enough. And personal headcanon? This girls handwriting is abismal, so her notes are kinda shit

But she genuinely tries so hard, and eventually pulls through like she always does

But God forbid you talk to her while she's pulling a Stress Allnighter? You're a dead man

Is definitely the reason M'gann learned how to make coffee
