Homework Help: Hard differentiation problem

  1. Jan 10, 2004 #1
    If [tex] \frac{\,df(x)}{\,dx} = g(x) [/tex] and [tex] \frac{\,dg(x)}{\,dx} = f(x^2) [/tex]
    Then what is [tex] \frac{\,d^2f(x^3)}{\,dx^2} [/tex]?

    differentiate [tex] \frac{\,df(x)}{\,dx} = g(x) [/tex]
    u will get [tex] \frac{\,d^2f(x)}{\,dx^2}=\frac{dg(x)}{dx}=f(x^2) [/tex]

    Is this enough
