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

The video tutorial explains how to find the cotangent of an angle given its tangent. It starts by introducing the problem and recalling that tangent and cotangent are reciprocals. Using a right triangle, the video illustrates the relationship between tangent and cotangent. Finally, it demonstrates how to simplify the expression by rationalizing the denominator, resulting in the final answer of sqrt 6 / 12.
