Use cofunction identities and trig identities to find the indicated trig functions

The video tutorial explains how to determine the cotangent of 60 degrees using cofunction identities. It begins with a problem involving the tangent of 30 degrees and introduces the concept of cofunction identities. The tutorial uses the unit circle to illustrate the relationship between sine and cosine, and applies these identities to solve the problem, showing that the tangent of 30 degrees is equivalent to the cotangent of 60 degrees. The video concludes by reinforcing the equivalence of these angles.
