In a way I think being able to derive a formula is a much more valuable skill than rote memorisation, especially in higher education. That being said I’ve also done this when I was just lazy and didn’t remember my lessons…

0ops@piefed.zip 20 hours agoLol I’ve had to essentially derive formulas that I should have memorized mid test before. Or reverse engineer examples from other questions to figure out the concept needed for another question (again, should have known that going in). I used to take absurdly long tests due to stunts like these, but tbh it usually worked. I distinctly remember discovering how logarithms worked mid-test at some point, for example

Yeah hell my statics lecturer encouraged it

Exactly. Tho i only had 45 minutes usually cause thats how long my classes in primary were.

Reminds me of highschool math. At some point you needed a graphical calculator, you could load programs into them but that required hooking them up to a computer with a crazy expensive data cable. So I found a schematic, ordered the components for a fraction of that price and learned to solder. It looked ugly AF, but it worked. Next step I wrote a program containing the formula’s I needed, uploaded it and installed a program which hid your program menu until you pressed a certain key combination. It could even simulate a hard reset, as you could get spot-checked and asked to do just that.
I could also have memorised the formula’s, but that wouldn’t have been fun. And unlike all those formula’s I still use my soldering and programming skills. 😋

Respect dude. Those cables are stupidly expensive (to match the calculators I guess), I just bit the bullet on mine

Well, it did help that they used a simple serial connection back then and didn’t require any advanced electronics. Just a bunch of resistors and basic stuff like that. All relatively large components that are easy to solder with what I had back then. I’m not sure how easy it would be these days with USB.

USB is actually really easy too. It’s only four wires.
