Polar form of a complex number, trig … WebI learned cis in high school in the US for 10th grade. Basically the whole thing was you could represents points on a 2D plane with complex numbers and then you could transfer them to polar coordinates using the equality for rcis (theta) = re i (theta). Other than that I see it used fairly commonly for electrical engineering stuff.
