Solving for tangent of a multiple angle

The video tutorial explains how to solve a tangent equation without constraints. It highlights common mistakes students make, such as misunderstanding function operations. The instructor guides through solving the equation by evaluating the tangent function and finding angles where the tangent equals -1. The solution involves adding multiples of π to account for the lack of constraints, and the final answer is derived by multiplying through to solve for X.

How do you find the general solution for X when tangent of X/2 equals -1?

What is the final expression for X after solving the equation?
