How to evaluate the half angle for the tangent function

The video tutorial explains how to evaluate the tangent of a half angle using specific formulas. It begins with an introduction to half angles and their representation, followed by a detailed walkthrough of evaluating the tangent using two different formulas. The instructor addresses common misconceptions, particularly the confusion between theta and theta over two, and demonstrates the correct approach to solving the problem. The tutorial concludes with the final evaluation and simplification of the expression, ensuring students understand the process and can apply it independently.
