Differentiation
Differentiation The differentiation is to find the amount of change at a point on a graph f(x). This is like the process of finding the slope of the tangent line when you can draw a tangent at a point on...

Triangle and Tetragon
Triangle Regular Triangle The lengths of the three sides and the angles are the same. The size of each of the three angles is 60 °. It is the only triangle in which the inner center, circumcenter, and center of...
Radians
Degree ‘Degree’ is one of the units for measuring angles. When rotated one turn, it becomes 360 degrees. ‘Degree’ is the most commonly used unit. Radian ‘Radian’ is the ratio (= l / r) of arc length (l) divided by...
Pythagorean Theorem 2
Pythagorean Theorem When the three sides of a right triangle are a, b, and c, and the longest side is c, the following equation is always true. The areas of a square with sides a, b, and c is a...
Geometric Series
Geometric sequence is The geometric sequence is a sequence in which each term has a constant(common) ratio to its preceding term. For example, the geometric sequence with the first term ‘a’ and the common ratio ‘r’ is as follows. \[...
Fourier Series 2
Fourier series The Fourier series is an infinite series that expresses a periodic function that repeats a certain part as the sum of simple trigonometric functions. A simple trigonometric function consists of a smooth surface wave. If you keep adding...

Normal Distribution
There are 10 black stones and 10 white stones in your pocket. What is the distribution of the number of black stones when I take out 10 randomly? Normal distribution Gauss in Germany has researched how much error is made...
Lorenz’s Waterwheel
Lorenz’s waterwheel Let’s say you have a waterwheel with a bucket with a small hole in the floor. When water drips from the faucet above, the bucket runs down and spins. Then, let’s predict which direction the waterwheel will turn....
Life Game
The Life Game is a cellular automaton devised by the British mathematician John Horton Conway in 1970. The universe of the Game of Life is an infinite two-dimensional orthogonal grid of square cells, each of which is in one of...
Binary Counting
Binary Binary is a method of representing numbers using only two numbers, 0 and 1. In the case of the decimal system, rounding occurs when 9 is added to 1. In the binary system, adding 1 to 1 does not...
