As time goes on, I grow more disillusioned with quantum field theory.

Yes, I just now figured out how it works (I had never heard of ParametricNDSolveValue before now). Thanks!

This is very nice! That I have to pick an upper limit of x is no problem. I also have two cases (in the list) where the upper limit of the integral looks like (1-x)^2. Would that case also work with NDSolveValue or ParametricNDSolveValue?

yes f[g[x]] that should match.

Sow? Reap? So we're farmers now?! Nice solution. I'll wait for more answers/comments before accepting this one

f[] and f[x,y] do not match.

Does this give the replaced expr as output? I should have said that outputting the replaced expr is needed, and I also need to store the variables on the side.

comment Quartic equation
I ran into similar issues; basically, you have two choices: 1. Compute the various cases by hand, and hard-program the correct values using Piecewise, or 2. Insert I*e into the square-root expression appropriately, and take the Limit as e->0. Mathematica will give a complicated answer but should result in correctly chosen branches.

comment User-defined template; removing repeated text (v 9.0.1)
Thanks for your answer (from 1.5 years ago). Do you know if the situation is any different in v10?
