What Is Derivative of (f²(x))? I am confused with that square sign thrown in there.

So then would the second derivative be: d/dx f'(x)(f(x)*2= [2 d/dx f''(x)f(x) +f'(x)f'(x)] = 2f''(x)f(x) + 2f'(x)f'(x) would that be right, pulling the 2 out in front?

Great, Just want to make sure. Thanks again, defunkt
