    also school never teaches what you use this shit for. I coincidentally found a real use for math functions when being taught a real use for geometry in steel trades class, one that removed any need for me to use hand drawn geometry for any of the work we were doing. Thankfully the teacher understood after a bit and said “oh shit you’re right” and accepted the math class style “show your work” instead of a drawing the size of a full sheet of plywood spanned over several desks

      Yes, this is so important.

      I had the advantage of making video games as a kid, so I had plenty of practice with trig functions trying to get my in-game spells to work so I knew their value first hand.

      I also made it a point to learn early on what calculus was about after hearing desperate stories is people hating the pointless thing. That also eased on the learning, which is the only reason I was top of the class.

        quaternions were also amagic discovery in game dev. its like I don’t understand it at all but at the same time it just works and makes sense and you can do simpler math on them just as cluelessly and just fuck around until it behaves as envisioned. It also solved my drone getting raped by gimbal lock back when the only way to have a drone was to diy one.

          Ohh, I love using quaternions but I don’t like learning about them as much. They’re both complicated but so easy somehow.

      Horticulture class taught me why the quadratic equation is important.

      “fArMerS ArE DumB!”

      Yeah. We had to spread fertilizer for max efficiency. Also learned matrices in that class.
