Mathematically speaking, the binomial coefficient is r the number of combinations of items that can be used to form a set n of items, or we can say that this coefficient is the number of ways to choose an outcome in an unordered way from th...

Ceiling division returns the nearest integer that is greater than or equal to the current answer or quotient. In Python, we have an operator // for floor division, but there is no operator for ceiling division. This article will discuss the...

Trigonometry is a field of mathematics that studies the relationship between the angles and side lengths of triangles. The relationship between angles and sides is calculated with the help of some special operations, such as 正弦 ,,,, etc...

sine The inverse of a function is called arcsine . Sine is equal to the ratio of the side opposite the hypotenuse to the longest side. sine The inverse of the function calculates the angle between the two sides. Assuming we have an 角度θ...

If we have two numbers a and m , then a the modular multiplicative inverse of is m modulo x if: a * x % m = 1 In this case, the multiplicative inverse exists only if a and m are relatively prime, that is, if the greatest common divisor of a...

This tutorial shows how to draw a grid on a plot in Python Matplotlib. We will use grid() the function to achieve this. It also shows how to use grid() the function parameters to customize the color and shape of the grid, or even draw only...
