@MarcoB here is an example showing Subst Steps[Int[Sin[x]/Sqrt[1 + x], x]] after loading Rubi. The steps with Subst on them are now displayed on the console window.

If you run ??Subst you will get at least a basic idea: "Subst[u,x,v] returns u with all nondummy occurrences of x replaced by v and resulting constant terms replaced by 0." You will also see the code for Subst, which might help.

It looks like parsing of Rubi ouput? this recreational-challenge-best-looking-output-for-rubi-integration-steps question has good info on Subst. If you are looking for an internal function to modify Rubi's output may be you can ask at Rubi forum as the Author Albert Rich reads that. He might be able to help better on this. | |
