# Interactive 3-D conic sections graph

By Murray Bourne, 10 Mar 2012

I recently added the following 3D interactive graph page to the Plane Analytic Geometry chapter in IntMath.

A "conic" curve is what you get when you slice a double cone by a plane, at different angles.

For example, a horizontal slice gives us a circle, and if we change the angle of the intersection plane slightly, we'll get an ellipse.

You can explore how to obtain a parabola and a hyperbola as well. This would work well with an Interactive White Board.
