This lecture is part of an online undergraduate course on complex analysis. • We show how to express mutliplication of complex numbers using polar coordinates. As applications we show that complex numbers all have n'th roots, and derive the formulas for sin and cos of multiple angles. • For the other lectures in the course see • Complex analysis
