How do you know who is failing there? The Gif's generator or the renderer?

comment How to do algebra on unsolved integrals?
@JerryGuern The form I used here is useful in more general situations where you have AND/OR clauses. For this particular problem your way is enough

@MichaelE2 No, I got it. Now Jerry is working with indefinite integrals and it works. Not for definite integrals, though

Just show how do you call your functions and how to get error, yes

comment Series expansion of InterpolatingFunction obtained from NDSolve
I believe trying to get orders higher than the ODE itself is doomed. Can't you try to fit the points with a nice model?

comment How can I get numerical answers to integrals involving the error function?
BTW, I see you've been around for about one year, but you don't vote too much and you usually don't accept answers to your questions. So, let me remind you: 1) When you see good questions and answers, vote them up by clicking the gray triangles, because the credibility of the system is based on the reputation gained by users sharing their knowledge. 2) Please remember to accept the answer, if any, that solves your problem, by clicking the checkmark sign! (On your past questions TOO!)
