Here, only one planet shares the same sun with the Earth. The Earth remains unchanged, while you can adjust the parameters of this planet's orbit: Apoapsis (a+c) and Foci distance(2c).just slide the control bars a little to feel the changes in the orbit. Now let's use the sliders to understand how a, b, and c affect the ellipse.[br]Have fun!

Given [math]\frac{x^2}{36}+\frac{y^2}{27}=1[/math], find a, c; [br]set sliders (Foci distance?, Apoapsis?) to verify orbits of the planets.
Set Foci distance=4 and Apoapsis=7 , calculate b and write the equation.[br]
