To square a complex number, square the length, and double the angle. A vector is a directed line segment, an arrow if you will. Think of a complex number, z = a + bi, as a vector from the origin (0,0) to the point (a,b). In polar form, z can be written in terms of r, the distance from the … Continue reading Square of a Complex Number
