Hey whats up,
The problem is....find the derivative of: y= x^2 sec(x5) My question is...Would I start off by using the product rule and combine the chain rule with it, with x5 being the inner function and sec(u) being the outer function? thanks...

That is correct, use the product rule then the chainrule.
