Homework Help: What is the step of integrating this?

  1. Jun 4, 2010 #1
    1. The problem statement, all variables and given/known data
    I need help in finding the answer of this integration:

    [tex]\int \frac{d^n [(x^2-1)^n]}{dx^n}dx[/tex]


    I have no idea how to even start, please at least give me hints how to substitude.

    Thanks

    Alan

    Doesn't the fundamental theorem of calculus say that


    [tex]
    \int \frac{df(x)}{dx} dx = f(x) +
    [/tex]

    ? And

    [tex]
    \frac{d^n [(x^2-1)^n]}{dx^n} = \frac{d}{dx} \frac{d^{n-1} [(x^2-1)^n]}{dx^{n-1}}
    [/tex]
