Matlab

(a) Use roots and zplane to plot the four roots of unity, i.e., the roots of the equation z^4 = 1

Check your answer by making sure that there are four s in the plot, and that one of them is at z = 1.

(b) Repeat (a) by plotting the eight roots of unity.

(c) Repeat (a) by plotting the twenty roots of unity. Note that here you may wish to use

the zeros command to simplify your MATLAB code.
