The purpose of this question is to calculate the three cubic roots of a complex number. A complex number is of the form a + ib where i is v-1. The magnitude r of a complex number is Vab. The complex number a + ib can be written as r(cos θ + i sin θ). Therefore a -r cose and b rsin0 and b/a (r sin0)/(r cos0) - tane e- arctan(b/a). The 3 cubic roots of a complex number are...
