Did you learn trigonometry rules off by heart at school and how did you manage to survive it?
Actually, the idea of learning 32 of them and reciting in class sounds a bit 19-century to me.
I was even more disappointed when I opened an English Maths textbook and didn't see any signs of such terrifying practice.
Did anyone here learn it, and how did you manage to survive???
PS The worst part is that we have to be able to recognise them pronounced and pronounce them, and not only be able to write them...
