# Math Help - Integration

1. ## Integration

Hi, I need help on this weird looking integral:

int_{x^3}^{x^2} dt/(1 + t^2)^3

How would you start this problem when the limits of integration are not values but rather functions?

Thanks

The same way you do any other integral. It's just that, instead of a constant, the Reimann integral will now be a function of x.

Do you need help integrating dt/(1 + t^2)^3?
