derivatives of trigonometric functions

Let us solve problems on derivatives of trigonometric functions

Find the derivative for the function y = cot 9x.
Solution:
Step 1: Given function
y = cot 9x
Step 2: Differentiate the given function y = cot 9x with respect to ' x '
= - cosec² (9x) (9)

= - 9cosec² (9x)
Example 2:
Find the derivative for the function y = tan^-1 (6x).
Solution:
Step 1: Given function
y = tan^-1 (6x)
Step 2: Differentiate the given function y = tan^-1 (6x) with respect to ' x '
= 1/1+(6x)^2 (6)
