Evaluating the composition of Functions using Right Triangles

The video tutorial explains how to evaluate the composition of the cotangent of the inverse cosine of 8/X. It begins by setting up a triangle and ensuring the angle is in the first or second quadrant. The Pythagorean theorem is applied to find the opposite side of the triangle. The tutorial then calculates the cotangent of the angle and rationalizes the denominator to provide the final solution. The process is explained step-by-step, ensuring clarity in understanding the trigonometric concepts involved.
