Homework Help: Finding derivative of f(X) = sin(cos(x^5))

  1. Oct 24, 2006 #1
    alright so i was given this problem:
    f(X) = sin(cos(x^5))
    and it tell me to find the first derivative of it.
    would i first solve the derivative of (cos(x^5)) first and then that answer with sin?
    or would i use the chain rule?
    thanks in advanced.

    Chain rule.

    Start by putting [itex]u=cos(x^2)[/itex] and [itex]y = sin u.[/itex]
