Derivatives of Trigonometric Functions

This video tutorial explains how to differentiate the trigonometric functions sec x, cosec x, and cot x. It begins with an introduction to the differentiation process, followed by detailed steps for each function. The chain rule is used for sec x and cosec x, while the quotient rule is applied to cot x. The video concludes with a summary of the results and encourages viewers to refer to formula books for these standard derivatives.
