Math 1200: tutorial 5 for oral presentation during tutorial 6 on thursday june 6, 2019 at least 4 of you will be called upon randomly to present your solution orally to one of the questions below during the start of tutorial 6 1. verify iy r - iy (z2) y 2i (z-2) and use for the following (a) identify the graph of |z + 45 in the complex plane (b) identify the graph of (1i)z + (1- i)z = 2. (c) find the equation (in terms of zz coordinates) of the line 2y 4 - (d) identify the graph of iz 2 1+ i 2. explain with a picture (drawing of the unit circle in the complex plane) why there two complex numbers z such that 21 = 1 and that satisfy the equation |2| = |z - i l. find both such complex solutions and express them in euler form z rei and in the usual form za+ bi are 3. solve the quintic equation 25- v3+ i = 0.
