Question

f(x)=sin2x + cos(^3)x . Find f'(x)

Answer 1

f'(x) = 2cos(2x) +3 cos^2(x)(-sinx)

Answer 2

Can you show steps?

Answer 3

there are no steps the deri od sin 2x is cos 2x (2) and deriv of cos ^3(x) is 3 cos^2(x) (-sinx)

Answer 4

deriv of sin u us cos u (du/dx) and cos ^3x is of the form u^n which derives as n u^(n-1) (du/dx)

Answer 5

Okay , thanks !
