Purplemath—Parabolas

Don't let parabolas throw you for a loop. Learn 'em, love 'em, maybe even graph 'em.

Paul's Online Math Notes—Ellipses

On even the most treacherous math problems, Paul always has our back. Tackle ellipses with him, and give him a high-five every time you solve one.

Coolmath—Graphs of Hyperbolas

Looking for a different way to graph hyperbolas? Here's one, and it works pretty well, too.

Cutting Conic Sections From A Cone

Watch in complete silence as the conic sections are cut out of a set of real-life cones. Riveting.

Elicia Team—Ellipses

A 3D rendered film showing different ways ellipse can be drawn. Very classy.

Conics—General Equation and Eccentricity

This guy uses c for the distance from the center to the foci, instead of f like we do. Otherwise, what he says is solid.

Khan Academy—Intro to Hyperbolas

Khaaaan! Academy covers the hyperbolic basics. His neon colors and soothing voice will lead the way.

Games and Tools

Math Playground—Project T.R.I.G.

Test out your parabolic skills with this game demonstrating projectile motion. It’s like Angry Birds with math and less property damage.

Interactive Mathematics—Interactive 3-D Conics Graph

Click and drag around the cross-section of a double-cone, to see what its insides look like. Don't worry, it's not gross, it's a conic section. Well, unless you're grossed out by conic sections. Then it is gross.

Web Graphing—Analyze an Ellipse

Plug in an ellipse equation, get an ellipse graph in return. This is an equivalent exchange we can get behind.
