Sorry about that, just a typo. But it is not possible to plug in every single point that encircles the RHP of S-Plane to see how many times the nyquist plot encircles -1 to determine the stability. So my question is what are some key points that I need to plot so I can determine stability of a...

I am trying to understand how to draw nyquist plot. Lets say the transfer function is Subbing in jω for s, ***Note: should be (jw)^4 , (jw)^3, (jw)^2 Then separating the Real and Imaginary part, So when w = 0, in the nyquist plot it is infinity w = infinity, it is 0 Imaginary intercept is...
