So I've got this problem.
Usually when doing division of complex numbers, I like to convert into polar form, then divide them.
So I'm trying to do a problem on the internet
it's
-j50 / 5 -j10
Now I've seen folks do that multiplying by the complex conjugate bit and that's fine, however I would very much like to convert this whole thing into polar and divide from there.
Now 5-j10 no problems... I hope
Sqrt(5^2 + 10^2)
and
tan^-1(-10/5)
= 11.18 <-63.43
Great
But what about the -j50 up on top, all on it's lil lonesome?
Now I've been taught that, this is equaled to 0+(-j50)
But I mean what does that even mean, when I say for eg.
sqrt(0^2 + (-50)^2)
Just returns a dirty big math error. Same with the tan-1 (-50/0)...?
