Hi, I'm trying to figure out how to integrate a^x/x!
(If you read it aloud it's A to the Xth power divided by X factorial)
a is a constant and x is a variable.
The limits are from 0 to N.
Even if you don't have the answer, if you have any tips on how it should be solved, I'd appreciate it. Thanks SoooooO much!

I tried using gamma(x+1) = x! and integrals.wolfram.com,
but couldn't find an answer for this problem. I also
ran it through Maple. No luck. For a start, why
not try a = e and estimate the integral using
a Riemann sum? At least you might get
a feel for what's going on. There seems to
be no way to do this with antiderivatives.

no be counted if it is log for the two denominator and numerator then write log(a million+ax) -log(a million+x^2) use u.v rule in the two and combine u get after using limits is Ans:a+(log(a million+a^2))/a -2arc tan (a) I.e. 2 tan inverse of a

so it wuld be a^x/x....duhh :-P
just substitute numbers in for the variables/consanant until you get a good answer
