Homework Help: D/dx of the integral from 0 to x^3 of ln(t^2 + 1)

  1. Apr 11, 2010 #1
    [tex]\int_{0}^{x3} ln(t^2 + 1) dt[/tex]

    ^take the derivative of that...sorry the upper-limit is x3 NOT 2x.

    how is the answer 3x2 ln (x6 + 1) ?

    Use the chain rule and the fundamental theorem of calculus. And show us your attempt.
