1. TransendentialPI

as long as f(x) is continuous and differentiable, $\int\limits_{- \infty}^{\infty}f(x)dx$ is there ever a time we woukd not choose 0 as c in$\int\limits_{- \infty}^{c} f(x) dx + \int\limits_{c}^{\infty} f(x) dx$

It's possible that a function is not differentiable at multiple points. Then you would continue to break it up like you've show above and take the limit wherever it is discontinuous.

improper integrals huh

4. TransendentialPI

OK, thanks, that's what I was thinking!

5. lgbasallote

you can choose 1 as c or whatever...as long it's within -infinity and +infinity
