so far,

f'(x)= 7(x^2 - [e^(2x)] + [sin^3 (x)])^6 * (x^2 - [e^(2x)] + [sin^3 (x)])'

= 7(x^2 - [e^(2x)] + [sin^3 (x)])^6 *@@@@@@@@@@@@@@

for @@@@@@@@...

i know i have to derivate (x^2 - [e^(2x)] + [sin^3 (x)])'

i was wondering if i just derivate like 2x - 2e^2x + 3(sinx)^2 (cosx) ?

if so, do i have to derivate "x" from"

(sinx)^3

3(sinx)^2 (cosx) <--- from here, do i have to derivate "x"? like 3(sinx)^2 (cosx)(x)' ?
