In general, if you know the trig ratio but not the angle, you can use the corresponding inverse trig function to find the angle. This is expressed mathematically in the statements below.

Inverse trigonometric functions are called "arc" functions because they essentially find the angle (or arc length) that corresponds to a given trigonometric ratio.

Knowing trig identities is one thing, but being able to prove them takes us to another level. In this unit, we'll prove various trigonometric identities and define inverse trigonometric functions, …
