Solving an equation with tangent with no restrictions

The video tutorial explains how to solve a tangent equation, initially within the interval of 0 to 2π, and then extends the solution to include all possible angles by removing the interval restriction. It covers the concept of tangent on the unit circle, the periodic nature of the tangent function, and how to express solutions in a general form using π. The tutorial emphasizes understanding the infinite nature of solutions when constraints are removed.
