It has no elementary form
I was just curious if you could do it as a power series.. or is that just pushing it?
Not the answer you are looking for? Search for more explanations.
yeah, but that isn't an elementary form, ie. it can't be written as a finite sum of polynomials and special functions. You could use the infinite series to approximate it but it will never have a finite form.
Hmm alright, probably won't have to worry about it for the exam then :P
definitely not, but if you are interested it is a form of a special function called the exponential integral denoted Ei(x). Far more integrals are not solvable than are solvable, but i doubt you'll ever be given a problem without a solution in a basic calculus class.
MIT Prof Denis Auroux addresses the integral to this function in this lecture beginning about 42 mins http://www.youtube.com/watch?v=YP_B0AapU0c&feature=BFa&list=PL4C4C8A7D06566F38&index=16
He is not integrating the function, he is changing the order of integration of a double integral. Just because you can rearrange in a double integral does not mean the inner integral is elementary.
I wasn't disputing your point. I was saying a very smart guy is talking about the same thing. :)
