Polar and Complex

This week, we are exploring the relationship between polar and complex coordinates. We start by changing complex numbers into their trigonometric form. Then we learn how to multiply and divide these complex trigonometric numbers, use de Moivre's theorem and finally, find the nth root of a complex number.
