Learn how to find the change in theta for a triangle, related rates

The video tutorial explains how to solve a rate of change problem involving a right triangle. It begins by introducing the problem and identifying the known rates and variables. The instructor then sets up a trigonometric equation using sine to relate the sides and angles of the triangle. The process of differentiation is explained, including the application of the chain rule. Finally, the instructor solves for the rate of change of X, emphasizing the importance of not simplifying too early in the calculation.

Explain how to differentiate the equation with respect to T.
