Chain rule isn't required for C2. You will come across it in C3.

Chain rule is C3 it deals with functions, within other functions i.e. f(g(x)) such as e^3x

The first rule y=[f(x)]^n in chain rule of differentiation is similar to the no.7 one of c1 differentiation to me . Is there any difference between them??
Thank you !

Ps. Sorry, poor english :s

If you put f(x) = x in the first rule of the chain rule page you get the basic result you learnt for C1.

The "first rule" on the chain rule page is itself just a special case of the second line which is what most people learn.
