Hello,
I dont have the strongest math foundation, so please excuse me if this is a dumb question.
I was integrating the following in Maple:
which produced the answer:
I've read that the erf is the error function but I don't really understand what it is. How can I obtain a 'Real' value for this?
Not quite! But good guess. It comes from a Maclaurin series. The difficult part comes from why the following step is justified . The idea is that and so by the Weierstrass M-test we may conclude that the sum is uniformly convergent and thus the interchangeability of the series and the integral is justified.
