Question

What do u mean by Parabola Circumstances?

Answer 1

Formally, a parabola is defined as follows: For a given point, called the focus, and a given line not through the focus, called the directrix, a parabola is the locus of points such that the distance to the focus equals the distance to the directrix. Note: It is a common error to call any u-shaped curve a parabola.

Answer 2

 A perfect parabola is a curve where the distance between a fixed point and another fixed line is the same at all points on the curve.
