When we talk about the inversion of trigonometric expressions, what we're really discussing is the process of determining an angle when we have a particular trigonometric value. This process is largely dependent upon inverse trigonometric functions: the arcsine, the arccosine, and the arctangent. These are commonly represented as sin^-1, cos^-1, and tan^-1. These specific functions are useful in that they offer us the corresponding angle for a given trigonometric value.
