# Integrating a differential form on a manifold without parametric equations

I am sure that this can be done, but I haven't been able to figure it out, Is there a way to integrate a differential form on a manifold without using the parametric equations of the manifold? So that you can just use the manifold's charts instead of parametric equations? If you a function mapping a portion of the n-1 plane onto an n manifold M say $c:[-1,1]^{n-1}\rightarrow\ M$ can't you use the pullback to integrate a differential form alpha? $\int_{M}α = \int_{[-1,1]^{n-1}}c^{*}α$. I read that this could be done, but every time I do the a calculation the integral turns out really weird, maybe an example would help?
