19 сент. 2023 г. · The Parabola. Note. As described in the introduction to Chapter 3, Menaechmus introduced a parabola as an intersections of a plane with cone.

Оценка 5,0 (1) The document defines a parabola as a conic section where the distance from a fixed point (the focus) to any point on the curve is in a constant ratio.

Definition: A parabola is the set of all points in a plane equidistant from a particular line (the directrix) and a particular point (the focus) in the plane.

What is different about this equation? (y-2)² = x + 1. What do you think it will look like? The y is squared instead of the x. will be a sideways parabola.
