The student will take derivatives of functions involving the trigonometric functions.



1. Collect Homework.

2. Recall:

and the Definition of the Derivative.

3. Derivatives of the six trig functions





Now determine the derivatives of cot(x), sec(x) and csc(x) using the quotient rule and the derivatives of the sin(x), cos(x), and tan(x).

4. Examples
