Use cofunction identity to solve trigonometric equation

The video tutorial reviews identities, focusing on cofunction identities and their transformations. It explains how to solve trigonometric equations using the unit circle and reference angles, and how to find solutions in all quadrants. The tutorial also covers the tangent graph, emphasizing its periodicity and how solutions repeat every π.

What is the period of the tangent function and how does it affect the solutions?

Describe how to express the general solution for tangent equations.
