Math Function Guide

This is a collection of math functions for lookup and reference. Functions are a very useful tool in applied mathematics, and as computers become more prevelant they are the bread and butter of the modern mathematician, hobbyist, or layman. Each function is linked to a page that describes how it is used and its input and output.

Trigonometry

Given the angle of a right triangle, returns the ratio of the triangle's adjacent side over its hypotenuse.

Given the angle of a right triangle as input returns the ratio of the triangle's opposite side over its hypotenuse.

Given the angle of a right triangle as input returns the ratio of the triangle's opposite side over its adjacent side.

Arithmetic

Returns the greatest common denominator of the two numbers a and b.

Returns the Logarithm of the number x with of base b.

Returns the remainder of dividing a by n.

Returns the square root of n.

Returns true if the number n is prime, false otherwise.

Set theory

Returns the intersection of the two sets a and b.

Returns the largest number in the set s.
