Trigonometric Functions
For Calculating derivatives of trigonometric functions we use the following definitions:
Note: the derivative of functions that begin with a c (cos, cot and csc) are negative.
For example:
3.1 
3.2 
3.3 
3.4 
For practice, find the derivatives of the following:
3.5 
3.6 
3.7 
3.8
