Yeah, so I can't figure out how to find the integral with respect to x of the following
cos(x) / (1 + x).
how would I do this?
thanks for any help
What it means old son is that there's no answer in terms of a finite number of elementary functions.
If you haven't met the sine-integral Si(x) and cos-integral Ci(x) functions then I would be mighty surprised to see them required on your test ....... Where has the question come from?
Are you sure you not asked to get definite integrals, say form 0 to oo?
