What Are The Inverse Trigonometric Functions (Arcsine, Arccosine, Arctangent)?
Inverse functions are functions that provide a translation from the result of a function back into a value that was passed in to it. For instance: In mathematics, inverse functions are usually represented (as above) by inserting a -1 super-script between the function name and its parenthesis. This is because with multiplication, this is the natural way to do it: But in computer programming it is often difficult to represent a super-script in a quick and efficiently typed manner, so computer scientists usually use the classical naming, ‘Arc’ Trigonometric functions, which comes from the classical Greek word for ‘inverse.’ The inverse functions for trigonometry don’t have simple relationships to the actual lengths and angles that the basic functions do, and were only formally defined after the definition of Calculus. Thankfully, most calculators and computers actually implement the underlying calculus into a simple way to do it.
