/sci/, I just had my mind blown by pic related. My trig class never bothered to define sec, csc and cot geometrically; it was all strictly symbolic (and always felt a little arbitrary). I made it to calc 3 without being aware that a geometrical definition existed.

Did anyone else get let down by their trig class in this way? Or have similar after-the-fact revelations about something that really should have been mentioned in a class, but wasn't?
