Math tutorial for evaluating the composition of the sine and tangent function

The video tutorial explains the concept of tan inverse and how to determine angles that produce specific tangent values. It covers the representation of tangent as opposite over adjacent and as y over x on the unit circle. The tutorial also discusses constraints in finding solutions and concludes with a summary of key points.
