polar plot of n^2 = 1+g (g=a/b~10^4) and/ or p^2 = (1-g)/( (1+g)*cos^2(theta)) equations and how can I get a circle from this equation? Thanks

n and p are the unknown unknown variables. Others are known, theta is variable. So to plot n (independent of theta) and p with theta. Thank you

Ran in:
About the 2nd equation, you can plot it straightforward by plugging values for variables g and theta
theta = 0:pi/100:2*pi; %
g = -0.5;
p = sqrt(((1-g)/(1+g))*(cos(theta)).^2);
polar(theta,p)
