问题
For using reflexivity, I must somehow transform n + 1 to (S n).
This should be a rather simple transformation, but I don't know how to tell Coq to do it.
How do I proceed?

Since they are not equal, just equivalent, you can use replace (n + 1) with (S n) which will ask you to prove that fact. Or you can use rewrite with the correct lemma from the std lib, which is add_1_r iirc.
