# How would I integrate this

e^(i Pi)+1=0

∫ex3 dx ?

## The Attempt at a Solution

no idea

hsetennis
have you tried integration by parts ?

Villyer
I don't think you can using 'standard' functions.

There's no "nice" function that will be a solution to this integral. You need to write it out as a series and integrate term by term. Your solution will be in series form

e^(i Pi)+1=0
Hmm, then I must have done something wrong earlier. It's part of a larger integration by parts problem, and we haven't learned series yet.

e^(i Pi)+1=0
∫x2ex3dx

e^(i Pi)+1=0
Lol, never mind. I can solve this with U-sub.
