Exam Review Composition of trig function and inverse using x

The video tutorial explores the relationships between cosine, inverse cosine, tangent, and arc tangent. It begins by explaining the cosine of π/3 and its inverse, then transitions to understanding tangent and arc tangent using angles and triangles. The tutorial concludes by constructing a triangle to find the secant of an angle, emphasizing the use of trigonometric identities and relationships.

What is the formula for the hypotenuse in terms of X when using the tangent function?

Describe how to find the secant of Theta using the triangle created from the arc tangent of X.
