Use MATLAB Symbolic Math Toolbox to solve the following equations for s, where s is a complex number. Express your answers in polar form and sketch them on the complex-plane. (a) s = 4 (b) s = -4 (c) s = 16 (e) s5 = 32 (f) s = j (g) s = 2-j2 (d) s* = -16 (h) s5 = 2-j2 Repeat solving the polynomials in Problem using the MATLAB command roots. Convert the obtained results in rectangular form to polar (exponential) form using the MATLAB cart2pol command. Note: To convert from polar form to rectangular form, the MATLAB pol2cart command is used.
