Zomplex plane exercises. 1. Given :1 = 6 + 13' and :3 = 2 43'. Find the complex exponential forms of :1 and :2. Sketch .31 and z; on the complex plane and label with both complex rectangular expressions and complex exponential expressions for both :1 and :2. J. Calculate and plot the two square roots and then the four 4'11 roots of the real number 1 (one) on a complex plane unit circle. (Remember powers 3'\" in class. You can also approach this problem with 1 = ea\
