Integral e^x(t)

[uberathlete]

Hi everyone. This is an extension of a problem I asked in the Differential Equation forum but I think it's more appropriate here. I'm having trouble with this integral:

integral e^x(t) dt

I've tried substitution and integration by parts but get stuck in both. Grrrrrrr!! Any help would be much appreciated. Thanks!

There is no general answer to your question.
For example, if x(t)=t<SUP>2</SUP> then there is no simple solution.
