If you were asked to convert a complex equation to polar form :
$r\cos(\theta) + ir\sin(\theta)$
Does the angle have to be in radians for the value of theta or can the angle be in degrees too ?
In which form would the angle have to be in radians ?
[Math] Degrees or radians for angle in complex equation

Generally speaking, when you are doing calculus, only use radians, otherwise derivatives require an annoying conversion factor.
(In the case at hand, it doesn't make a difference, but it is unnatural to use degrees.)
