Day 1

Mm2g2c - Conics: Parabolas


What do you know about parabolas

What do you know about parabolas?


Parabolas

Parabolas

Definition (OLD): an equation in the form of or

Definition (NEW): The set of all points in a plane that are equidistant from a fixed line (directrix) and a fixed point (focus) which is not a line.

Lattice Points: points equidistant (2p) from the focus on the parabola
