Nope. "i" is electical current (though it's more customary to use
upper case). "j" is the square root of -1.
and that hypercomplex numbers include i, j, k, and maybe even other
terms, and I never understood where j comes from. Why is Python
better for using j?
Because that's the way we do it in electrical engineering.
Okay, so hold on a minute... a hypercomplex number is the sum of a
real number, some electrical current, an imaginary number, and k?
I don't know that EE's ever encounter hypercomplex numbers (I
certainly never have)
But they are very useful to represent 3D-rotation around an inclined
axis (look up quaternion rotation). I don't know whether EEs work in
aircraft navigation, but I suspect they do ;)
