if f(x) can be something like -x^2 there may not be a closed form solution in terms of elementary functions

Solved

Posted on 2006-04-14

It's been about 10 years since I last took calculus, and I seem to have forgotten some things. I'm ripping through my various calculus books (and diff eq) trying to find the answer, but I can't seem to find it. I'm also trying various substitutions to no avail. Here's what I'm trying to integrate:

INT e^f(x) dx

I can find INT f'(x)e^f(x) dx, but not it. Unfortunately, f'(x) is not a constant; it is a polynomial. I remember them telling us that not all functions (even continuous) can be integrated, but this sure feels like it should be integratable.

Thanks,

Daniel
