preCalculus 2017-2018: Conic Sections! (February)

preCalculus 2017-2018:
Conic Sections! 
(February)

Chapter 10 ScreenCasts



Chapter 10 was all about Conic Sections. First we learned about how to graph Conic Sections on the Cartesian Plane when the graph has horizontal or vertical symmetry: 
Ax^2+Cy^2+Dx+Ey+F=0. 

Then we talked about using Polar Coordinates to graph rotations: 
Ax^2+Bxy+Cy^2+Dx+Ey+F=0, B!=0. 

We also had fun with several applications: Parabolic Satelite Dishes, Elliptical Orbits and Whisper Galleries plus LORAN: LOng RANge Hyperbolic Navigation and Radar Systems!
