    Integration Pls Double Check - Possible Error?

    Can someone please double check this for me? It seems to be correct but the number I get is far larger than those obtained using non-algebraic methods of obtaining derivatives.

    Hello,

    Hmmm... Is it \int_0^{10} \frac 1{10} x^2 \cdot 4x +1 ~dx ?

    Develop as far as possible, because \int f(x) \cdot g(x) ~dx \neq \int f(x) ~dx \cdot \int g(x) ~dx !!!!

    I just saw that you double posted that question, that does not make sense.

    yeah it was [COLOR=#0000AA][FONT=monospace]

    <br />
\int_0^{10} \frac 1{10} x^2 \cdot 4x +1 ~dx<br />

    BTW, I double posted the question because I already attmepted it before and ended up with 0.4 whcih I was told was right but the answer did not make sense seeing how as I have already obtained the derivative using the midpoint rule, trapezoid rule etc.
