I have simple problem in derivative of trigonometric functions, can anyone show me the way to calculate the derivative of following function?
$$y = \sin^2 x (\cos x + \sin x)$$
I think the answer should be:
$$y' = (2 \sin x \cos x)(\cos x + \sin x) + (-\sin x + \cos x)(\sin^2 x)$$
Is the above answer correct?
Thanks in Advance...
