Theorem:-The sum of the focal diatances of any point on an ellipse is constant and equal to the length of the major axis of the ellipse.

What is the sum of focal radii of any point on an ellipse equal to ?

Find the sum of the focal distances of any point on the ellipse 9x^(2)+16y^(2)=144

Difference of Focal radii of any point is equal to the length of major axis

If the length of the major axis of an ellipse is 17/8 times the length of the minor axis, then the eccentricity of the ellipse is

Let the length of the latus rectum of an ellipse with its major axis along x-axis and centre at the origin be 8. If the distance between the foci of this ellipse is equal to the length of its minor axis, then which one of the following points lie on it

y-axis is a tangent to one ellipse with foci (2,0) and (6,4) if the length of the major axis is then [x]=_____

If the distance between the foci of an ellipse is equal to length of minor axis, then its eccentricity is
