It's quicker to relearn than it was to learn it in the first place, so there is that...
I'm having to re-learn matrix transformations but I can't even remember now if I ever did them, except that I must have, because they are required in certain subjects
Maths, Physics and Chemistry are the only subjects I've had to go back to, all the rest was useless.
Are you actually using the matrix transformations for real-world problems? I remember learning them in high school and thinking it was a waste of time.
I think I must have been using them in signal processing? I've just got this vague memory of 4x4 boxes
I was surprised to discover it's now a GSCE topic?
Nothing real world, but I'm interested in getting a hardware floating point chip to do 3D transforms, looks like is going to take forever because it's borderline kinda too much for my brain/attention span
"it's borderline kinda too much for my brain/attention span"
I know how you feel. From personal experience, I bet you are really good at other things though; Things that don't come naturally to a lot of number smashers. At least that's what I tell myself.
To get through matricies, I wrote a program on my TI-82+ that did the math and showed the work that I needed to copy down.
3D work. You an artist? Or for 3D printing?
