Mzybe I was a bit too harsh in my statements. I do get irritated when people talk about "memorizing theorems" and I also strongly dislike SRS

Well, I can see it being helpful in some cases, maybe for a beginner in languages, or for learning a new alphabet. But for languages especially I think SRS is more a problem than a solution. A language is also an organic entity, and to "learn" it by isolating words and playing a memory game is ineffective, and it doesn't really cement those words. Soon the srs session becomes a chore, one that pays little and unnecessarily taxes the brain. A far better solution is just reading. It's not hard to see why it's a much better option, in so many levels, than simply checking flashcards. Plenty of graded readers are available now for many languages.

They are just sophisticated reminders.
What techniques do you use to make sure you remember mathematics? What is your alternative?
Notebooks. I can only advocate for flashcard study if you have an exam tomorrow.
As with vocabulary in languages, how are you to know how relevant a theorem is going to turn out in the future? The time spent taxing your mid-term memory with flashcards is better spent reading on, where the theorems show up in their natural context, where you will either remember them or they can simply be checked from your notes; their repeated use will be exactly what SRS tries to emulate, refer to my note on the previous paragraph on reading.
I don't remember most trig identities, and they have seldom been relevant to me outside of a few applications in calculus (proofs where they are just a step in the process), but at least the laws of sines and cosines are so common that I simply remember them without ever actively comitting them to memory.
Programmers and mathematicians always say "I don't do arithmetic, that's the computer's job". The exact same principle applies to memory, and you don't even need a computer.
