    Basic integration question

    The solution to this problem is proving to be elusive, any insight would be appreciated!

    The integral from x to x^2, with f(x) = t^2, and I'm looking for the derivative of that. Thanks!

    Would it not be

    \frac{d}{dx}\left[\frac{1}{3}\left(t^3|^{x^2}_{x}\right)\right] ?

    right thats what I thought it was, could you also write that as : (1/3)(x^5+x^3) ? or am I missing another step somewhere?

    No... Watch

    \frac{d}{dx}\left[\frac{x^6-x^3}{3}\right]=\frac{d}{dx}(\frac{x^6}{3})-\frac{d}{dx}(\frac{x^3}{3})=6\cdot\frac{x^5}{3}-3\cdot\frac{x^2}{3}=2x^5-x^2
