Use quotient rule to take derivative with trigonometric functions

The video tutorial covers evaluating derivatives, focusing on using different methods to simplify expressions and find derivatives of trigonometric functions. It begins with a discussion on the preferred approaches to derivative evaluation, followed by simplifying expressions using trigonometric identities. The tutorial then demonstrates finding derivatives of trigonometric functions like cosecant and cotangent, concluding with a verification of the solution.
