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.
