The class checks to see if the formula for finding powers of a complex number works to find the roots too.  Pupils review the previous day's work and graph on the polar grid. The discussion leads the class to think about how to reverse the process and find roots. At the end of the 20th segment of 32, the class determines the formula for finding nth roots of any complex number.
