Question

(9) The sum of the distances to the two
focal points from every point on the curve
is
constant​

Answer 1

Answer:

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same
