Question

The equation of a surface in spherical coordinates is rho^2(1+2cos^2(phi))=1

Identify this surface;
what is its Cartesian equation

Answer 1

I know that we have to convert from spherical to Retangular or Cartesian and the transformati9on equations are :
rho= sqrt(x^2+y^2+z^2)
tan theta = y/x
cos phi = z/p

But i don't know how to apply it to the equation given because pieces seem to be missing
