I need a quick check on my math. Derivative of composite function y=sec^2(X) where X is a polynomial.(adsbygoogle = window.adsbygoogle || []).push({});

Does it equal:

y'=(secXtanX)(secX)(X)(dy/dx)+(secX)(secXtanX)(dy/dx)(X)+(secX)(secX)(dy/dx)

I'm a little confused on applying the product rule and the chain rule to this function.
