# 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.

Interactive 3-D conic graph

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.

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
a^2 = sqrt(b^2 + c^2)
(See more on ASCIIMath syntax); or
2. Use simple LaTeX in the following format. Surround your math with $$ and $$.
$$\int g dx = \sqrt{\frac{a}{b}}$$
(This is standard simple LaTeX.)

NOTE: You can mix both types of math entry in your comment.
