Integrating ∫ex3 dx: Utilizing U-Substitution

[e^(i Pi)+1=0]

Homework Statement

∫e^x3 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]

∫x²e^x3dx

 

[e^(i Pi)+1=0]

Lol, never mind. I can solve this with U-sub.
