TJ,

I think I see what you are looking for: An ellipse which is tangent 
to the two radial lines and the two end lines. confined between the 
two end lines--also tangent to the ellipse.

The stack below calculates the point on the ellipse where the tangent 
to the ellipse is parallel to the  radial lines and then puts the 
ellipse there. I have confined myself to the case where the major 
axis of the ellipse is parallel to the x axis. It gets grubby 
otherwise. This was fun. I hate grubby.

In the message box:

    go stack url "http://home.infostations.net/jhurley/EllipseInAbox.rev"

Hope this helps.
