Day 1 Mm2g2c - Conics: 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
Equation: ___________________________ p > 0, opens: _____________________ p < 0, opens: _____________________ Vertex: __________________________ Focus: __________________________ Directrix: ________________________ Lattice Points: ____________________ Equation: ___________________________ p > 0, opens: _____________________ p < 0, opens: _____________________ Vertex: __________________________ Focus: __________________________ Directrix: ________________________ Lattice Points: ____________________
