How to use the inverse tangent without a calculator

The video tutorial explains how to find the angle Theta using the tangent function. It covers the unit circle, reference angles, and the quadrants where the tangent is negative. The tutorial also discusses the restrictions on the tangent inverse function and how to determine the correct angle within these restrictions.

Describe the process of determining the reference angle for tangent in the second and fourth quadrants.
