Learn how use the quotient rule to take the derivative including cosine

The video tutorial explains how to find the derivative of a function using the quotient rule. It begins by defining the function Y as cosine of X divided by cosine of X, and then identifies the numerator and denominator functions. The derivatives of these functions are calculated, and the quotient rule is applied to find the derivative of the entire function. The final result is presented as the derivative of Y with respect to X.
