  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with: ```diff

Porbably too low for uni level but I can't find complex numbers in help school

Cartesian to polar:
(x,y) -> (r,ø)
r = sqrt(x²+y²)
ø = arctan(y/x)
Polar to cartesian:
(r,ø) -> (x,y)
x = r cos(ø)
y = r sin(ø)
if you get a negative angle from arctan, for example 30°, then the angle is 360°-30° = 330°

what about the quadrant?
