Inverse Trigonometric Functions

Definition

The inverse trigonometric functions are the inverse functions that finds the angle from a given trigonometric ratio.

Inverse trigonometric functions can be represented geometrically: arcsin, arccos and arctan. arcsin(0.5) is the arc / angle (as arc corresponds to angles in radians) that gives a trigonometric sine ratio of 0.5.

They can also be represented using the standard function notations for inverse functions. Eg. arcsin(0.5) = sin-1(0.5)
