Axes of an ellipse

  1. Mar 19, 2007 #1
    in my textbook says that a^2=p^2/(1-e^2)^2, and b^2=p^2/(1-e^2), are two axes of an ellipse, however there is no any proof as to how we can be sure that a and b are such axes. Where p is the focal parameter, and e is the eccentricity of the ellipse; a- is the big semi-axes, b- the small one.So i would like to know is there any proof that ensures us that the above expressions are indeed or represent the axes of any ellipse??
    I asked the assistant proffesor on my Analytical Geometry class, but she did not know how to proof it.

    Any help would be welcomed.
