5. Directly using the magnitude and angle information from the bode plots in the last please plot the corresponding Nyquist plots. (Note: each pole at origin/imaginary axis, means we'll take a small detour in the Nyquist path around that pole. If the Nyquist path detour is counterclockwise, it causes a clockwise semicircular loop of infinite radius in the Nyquist plot. Two poles on origin will cause two clockwise-semicircular-infinite-loops, i.e. a full circle. You'll have to read about the Nyquist plots of systems with integrators by yourself.)
