# What is the step of integrating this?

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

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

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

$$\int \frac{df(x)}{dx} dx = f(x) +$$

? And

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