Question

derivative of
${tan}^{3} x$
​

Answer 1

Answer:

To apply the Chain Rule, set u u as 3x 3 x . The derivative of tan(u) tan ( u ) with respect to u u is sec2(u) sec 2 ( u ) .

Answer 2

$solution \: = \\ \frac{d( { \tan }^{3} x)}{dx} = 3 {tan}^{2} x + \frac{d( tan x)}{dx} \\ = 3 {tan}^{2}x {sec}^{2} x \: \: \: \: \: \: \: \: \: \:$

This is your answer . Hope it helps you.
