Combining product rule with chain rule

  1. Nov 7, 2004 #1
    Hey whats up,
    The problem is....find the derivative of:

    y= x^2 sec(x-5)

    My question is...Would I start off by using the product rule and combine the chain rule with it, with x-5 being the inner function and sec(u) being the outer function? thanks...

    That is correct, use the product rule then the chain-rule.
