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 …

Learn about arcsine, arccosine, and arctangent, and how they can be used to solve for a missing angle in right triangles.

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

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

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

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

Graph of sine inverse function Principal value of inverse functions Evaluating ITF expressions Evaluating inverse (angle outside principal branch) Up next for you: Level up on the above skills and collect up …

You'll learn how to use trigonometric functions, their inverses, and various identities to solve and check equations and inequalities, and to model and analyze problems involving periodic motion, sound, …

What are inverse trigonometric functions? Inverse trigonometric functions are the inverse functions of the trigonometric functions. For example, the inverse of the sine function is the arcsine function, …
