day 6 - 9 sep

topic: power series

been a month. "reasonable posting schedule" my ass

[dude-study]

day 5 ~ 6 aug

topic: logic

somewhere in this mess there is something comprehensible.

[dude-study]

day 4 ~ 1 august topic: logic (it rhymes heh) proofs are fun!!!!1! (ugh, not yet. soon, maybe. hopefully by the time I take abstract algebra and real analysis)

[dude-study]

day 3 ~ 28 jul topic: functions i'm in this really weird situation where I have to take two successive classes at once (calc & linear alg. & vector calc & diffeq) so yeah, i'm studying functions at the same time as ODEs (lol)

[dude-study]

day 2 ~ 25 july

topic: introduction to ordinary differential equations

first set of notes for the semester ^_^

[dude-study]

day 1 ~ “a new beginning” ~ 23/7

topic: integration

this semester is gonna be…well…fucking difficult. that’s okay! at least maybe I’ll post at reasonable time intervals this time lol

[dude-study]

Your handwriting 😍 damn

ahahah, thanks :)

1000 followers!!!!

just checked into my studyblog for the first time in a while! thanks everyone!!! I promise I will be more active when semester starts again in 2 weeks.

I’m thinking about her again

Any mathematics can be discrete mathematics if you’re bad at spelling and do it privately

[dude-study]

woah... uni at 16? how tf did you do that? i'm impressed

in the Australian school system you normally start uni at 17 - I went up a grade in like primary school so I'm not *that* smart or anything 😂

day 53 ~ 10 jun don't you love exams

[dude-study]

day 52 • 15 may

minimalism

also wtf is induction??

[dude-study]

day 51 - 13 may back to paper for now. i found using digital notes had become a distraction and I needed to find a use for all the muji notebooks i bought in japan... also hi it's been like 3 weeks wha

[dude-study]

day 50 • 24 apr

hey y'all, it’s been a while :)

PS im getting used to real LaTeX now.

[dude-study]

day 49 • 15 apr pointing the desk lamp at the wall gives a nice ambience. lol

[dude-study]

latex is amazing learn it!!!

hey; could you explain LaTeX to an absolute newbie? where and how can I learn it?

A good introduction will get you on your feet fast. You will probably just need to do what I did and learn the rest as you go once you get familiar with it.

\section{Getting LaTeX}

First thing you want to do is get something that supports LaTeX that you can play around in. All of the following should be good enough for getting started. Some options are:

\begin{itemize}

 Overleaf online and mostly free and functional with a sign-in. I think you have to pay to store like over 2gb of documents on the cloud or something, not like that’ll ever be an issue really. I use this one. It is pretty good. Start with this one for online stuff but move on to something else if you don’t like it.

 ShareLaTeX, I’ve never used this but it’s online and free.

TeXmaker,This is free software, it’s the one I use and I like it.

MiKTeX, This is also free software but I can’t seem to get it to work on my laptop.

BakomaTeX, I’m told God uses this software. It’s not free, but it looks worth it.

If I recall correctly, Microsoft Word will support latex symbols and notation in “equation mode”.

LaTeX Base is an online compiler i just found with decent functionality for non-paying users.

And here’s a few more if none of those make you happy.

\end{itemize}

\section{LaTeX tutorial speedrun}

Let’s let ”YCH” stand for “your content here” for the sake of demonstration.

\subsection{Environments}

LaTeX has these things called “environments” which tell latex how to display the text. there are the various math environments which display math in different ways, the “itemize” environment that builds lists with the “\item” command, and more. To use an an environment, you need three lines of code, ususally.

\begin{environmentName}

YCH

\end{environmentName}

You will usually need to open the “document” environment and put everything you want shown inside of it, even your other environments. Like so:

\begin{document}

    \begin{itemize}

       \item here’s a bulletpoint.

    \end{itemize}

    Here’s just some plain text.

    \begin{equation}

        e^{ix} = \cos(x) + i \sin(x)

    \end{equation}

    Below will give us the same thing. It’s easier to type:

    $$e^{ix} = \cos(x) + i \sin(x)$$

    Note that in order to start a new paragraph in normal text you need to hit enter twice, not just start a new line.

\end{document}

There’s more about this below.

\subsection{Structure}

Use LaTeX’s commands to put in titles of sections, chapters, and whatnot wherever you type them, like these: 

\chapter{YCH}

\section{YCH}

\subsection{YCH}

\subsubsection{YCH}

\paragraph{YCH}

That will probably be enough for now.

\subsection{Math}

For an equation that shows up inline, you use a single “$” on either side of your equation, like this: $YCH$. Some people use “\( YCH \)” for inline math or something but that’s confusing. Don’t do it. For an equation that shows up on it’s own line, you use “$$” on both sides, like this: $$YCH$$. You can also try the “equation” environment like this:

\begin{equation}

YCH

\end{equation}

Next, we’ll need to know what to put in there. Here’s a a handy dandy little chart of things (that barely scratches the surface, really):

YCH_{subscript for your content}

YCH^{superscript for your content}

\mathbb{R} (the real numbers symbol)

\lim (the Lim symbol)

\sin, \cos, \tan … (You name the function, they got it.)

\frac{inline numerator}{inline denominator}

\dfrac{numerator that’s whatever fucking size it wants}{denominator that’s whatever fucking size it wants}

\sqrt{guess what this is, lol}

\left( YCH \right)  This makes parentheses that are the right size.

\yourgreekletterhere lowercase whatever greek letter that is

\Yourgreekletterhere Uppercase whatever greek letter that is

\int the integral symbol

\sum the big sigma/sum symbol

\forall the quantifier that is the upside down A

\exists the existential quantifier that is the backwards E

\in the “in” symbol, \ni the “in” symbol backwards, and \notin

\leq \geq, \neq the less than or equal to, greater than or equal to, and not equal to symbols.

\begin{cases} YCH1 & condition \ YCH2 & condition \end{cases} make a piecewise function.

\section{conclusion}

PRINT OUT THIS CHEAT SHEET AND KEEP IT WITH YOU, IT IS A GOOD REFERENCE.

For more comprehensive information, please see the LaTex 2e manual (PDF), a few youtube videos, stackExchange, and the internet at large.

Hope this helps. - Real

P.S. It’s pronounced Lay-Tech, not latex. In my experience, people will make fun of you if you say it wrong. They’re weirdly defensive about how LaTeX is pronounced.
