preCalculus 2015-2016 December
Conic Sections!
We spent all of December on CH10 Conic Sections. We talked about the General Form:
Ax^2+Bxy+Cy^2+Dx+Ey+F=0
and converting to standard form Parabolas, Ellipses, Hyperbolas using Completing The Square when B=0. When B was non zero, we converted to Polar Notation:
x=r*cos(theta), y=r*sin(theta)
We talked about the directrix, latus rectum, center, focus, parabolic mirrors, whisper gardens and planetary orbits! We even played with parametric mode and ballistic trajectories.
