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.

Review your knowledge of the inverse trigonometric functions, arcsin (x), arccos (x), & arctan (x).

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, which allow us …

Properties of inverse trigonometric functions Properties of ITFs Proving identities involving ITFs Using Trig identities on ITFs Expressing inverse in simplest form Evaluating compound ITFs Solving …

Plotting the graphs of inverse trigonometric functions can seem unintuitive at first. But don’t worry! All you need is the graph of the sine function and an inquisitive mind, and together, we'll successfully …

Basics and Graphs of Inverse Trigonometric Functions Intro to arcsine Intro to arctangent Intro to arccosine

Sal introduces arcsine, which is the inverse function of sine, and discusses its principal range.

In this video, we find the principal values of a few inverse trigonometric functions. The approach that we follow here is to figure out the quadrant first. And then find the angle in that quadrant that gives the …
