Revival the slide rule in education！: Mathematics Note -7 (essay)

"Revival of slide rule in education" Cram school instructor Rei Morishita 40

When I was a junior high school student, there was a "slide rule" in the curriculum of the class, and I remember buying a textbook and studying it myself because of the fun of its principle. Just as abacuses were required for commercial students, slide rules were required for science and engineering students. I'm not good at addition, but I could say that the slide rule is a magic stick that demonstrates outstanding power in multiplication, division, exponential calculation, and trigonometric function calculation. It can be said that it is a representative of analog type computers.

Of course, in terms of comprehensive functions, it is not as good as a digital computer, but even so, I think it is too much not to tell students about the existence of this calculator. As an application of the theory of logarithms in mathematics, the slide rule is worthy enough just as a teaching aid to teach students "visually" about logarithms. Computers are not just computers.

Leading the students' interest in only one direction is also negative in terms of diversity. 　

"The above is a letter to a newspaper company."

A slide rule is a tool that "visually" scales the mathematical concept of logarithm. The slide rule is divided into outer scale, inner scale, and cursor parts. In mathematics, there is a formula LogA+LogB=Log(A*B), but the scale of A (outer scale) is assigned with a logarithmic length scale on the scale, and the scale is moved to B (inner scale). Align "1" on the scale and read the scale of B with the cursor, it will be the "sum" of the logarithms of A and B, and as a result, the number A*B will be displayed. The prominence of the logarithm is deeply felt in the way that the sum of the lengths indicates the product. The same holds true for other calculations, such as the quotient for length differences.

This tool is a collection of mathematical, scientific and engineering wisdom that has been steadily continued since ancient times. It seems that the stupid officials of the Ministry of Education, Culture, Sports, Science and Technology are excluding it from school programs, as if "it is unnecessary because there is a computer". As I have said, slide rules are foolishly thought to be worth continuing to teach as analog calculators. I think it's a dangerous trend to eliminate all analog things while all phenomena are being streamed digitally.

The issue is that by rounding you drop some accuracy. It straddles the greatest price, which means it must converge much further to reach its final value. As you proceed, the quantity of terms you will need is smaller to get the very same precision.

How to Get Started with Log Calculator?

They are like the rules for different logarithms. Typical logarithms are extremely helpful in representing very big numbers or very tiny numbers. Natural logarithms may also be evaluated employing a scientific calculator.

It is likewise very convenient to introduce the idea of substitution, which is so helpful in calculus. Once an exponent is 1, the base stays the same. That exponent is known as a logarithm.

You may see the present math calculations in a more compact display that’s below the most important display of the calculator. This calculator gives you the ability to define your own functions to utilize in expressions. On-line calculator is totally free and is a simple method of problem solving.

The Downside Risk of Log Calculator

By going into the dimensions of your firewood stack, this calculator will let you know how many cords you’ve got. Hell, you can earn customized functions should you somehow don’t locate the one which you’re searching for. It usually averages out, because logs are ordinarily not so perfect, and frequently have boards that are below-grade and wind up in the firewood pile.

Casual savers may choose a reduce amount to contribute. It’s possible to even press-and-hold on any key to modify its function and size, developing a customized layout that perfectly fits the manner in which you work. This is among the reasons why you need to be careful if buying wood by these measurements.

A History of Log Calculator Refuted

You might need to reset some things like the variety of decimal places. Again logs are another means to compose exponents and that is that which we are interested in here. Use this calculator to compute the essential hard drive space you will want to realize your preferred record time.

Defining this value is optional, but if you would like consistent outcome, it is a great idea to specify it. Logarithm is believed to be among the basic concepts in mathematics. Logs are frequently used in chemistry.

When you have difficulties of any of these powers return to my page on powers. When you are requested to expand log expressions, your purpose is to express a single logarithmic expression into many individual components or components. The main reason for this is to be in a position to deal with logarithm of values away from the convergence region (and generally we would like to use the series for so narrow region as possible).

When large quantities of logs should be measured, one particular diameter reading by caliper at the mid-length of each log might be sufficient. It’s a polyhedron also referred to as hexahedron. To acquire porosity, read the value straight from the log.

Indeed, in case you go to the old and dusty books of any good university library, you ought to be able to get these previous books of mathematical tables. If you wish to execute an operation on negative numbers, you ought to use the button. You should conserve a copy of this, and that means you click the Print button and find a printout.

Assuming you’re growing continuously at 100%, we are aware that ln(2) is the sum of time to double. The all-natural log may be used with any interest rate or time so long as their product is exactly the same. Various amounts and terms will lead to different comparison prices.

Things You Should Know About Log Calculator

In this instance, both events were a result of the exact incident, therefore it only counts once. So I first should isolate that portion of the argument that has the ability on it.

After doing this, you add the resulting values to receive your final answer. It has to be a solution set. There’s nothing to be accomplished continuously, it will just continue printing the very same answers.

Knowing the way the test performs in your area will help you realize the results to anticipate from those variables. Engineers really like to utilize it. External equipment is obligatory for charge and discharge.
