I just got out of a differential equations exam. In that exam, i had to integrate e^x/x (e power x over x)(adsbygoogle = window.adsbygoogle || []).push({});

I worked it out on scratch, and i came up with this:

e^x = Sum(i=0->infinity){X^n/n!}

So dividing by x we get Sum(i=0->infinity){x^(n-1)/n!}.

By integrating we get e^x.Sum(i=0->infinity){1/n}.

The latter series diverges, so i concluded that we can't find a solution to that integeral. I re-checked the work that lead to that equation like four times, and it was all correct.

So could it be that the there was a fault in the exam?

HALP!!!

(sorry didn't use latex or whatever it is called to represent my calculations)
