Evaluate the Inverse of Tangent

The video tutorial explains how to find the inverse tangent of a given value using the unit circle. It covers the calculation of tangent values for specific angles and discusses the restrictions of inverse tangent, focusing on angles where tangent is positive. The tutorial emphasizes understanding the unit circle and the process of rationalizing denominators to find the correct angle, specifically highlighting the angles of 30, 45, and 60 degrees.

Describe the conditions under which tangent is positive.
