Question

Find the derivative of

\[y = \int\limits_{a}^{x^{2}\tan(x)} dt/(1+t^{2})\]

How do I do this? can I just insert x^(2)tan(x) directly into x and cancel out the integral?

Answer 1

you mean insert x^2*tanx into t to cancel out the integral...
yes but you must also multiply by the derivative....
