polar plot of n^2 = 1+g equation

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

[Mathieu NOE]

what are n , p and g ?

[Ismita]

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

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)

The first equation is not clear to me
