No. It’s more what the previous poster said about encoding rotation. It’s just not a xyz axes. It’s current, charge, flux as axes. The trig is how you collapse the 3d system into a 2d or 1d projection. You lose some information but it’s more useful from a spefic reference.
Without complex numbers you can’t properly represent the information.
Yeah a good friend of mine has a PHD in math. I asked him how he would describe math. His answer was a set of rules for dealing with numbers. What’s important is how useful the rules are.
Yup. When you have a circuit that is not purely resistive the inductive or capacitive load causes the voltage and current to not be in phase. It looks like ohms law is being violated. However the missing part of the energy is in the imaginary component to be returned latter.
I get the joke but Auschwitz was in Poland. They were careful to keep all the concentration camps out of Germany.
Yeah I remember when cmdrtaco was in charge. It was great back then. Now it’s full of anti woke stuff.
Yeah on table top space marines are the reference for other things. Other armies usually have a unit that is considered a SEQ (space marine equivalent)
If I put a number on them it would be 1 where as IG flashlight trooper would be 0.1 and a tank would be around 7-10
Yeah. The thing that made me “get” quaternions was thinking about clocks. The hands move around in a 2d plane. You can represent the tips position with just x,y. However the axis that they rotate around is the z axis.
To do a n dimensional rotation you need a n+1 dimensional axis. So to do a 3D rotation you need a 4D axis. This is bassicly a quat.
You can use trig to get there in parts but it requires you to be careful to keep your planes distinct. If your planes get parallel you get gimbal lock. This never happens when working with quats.
