# Interactive ellipse graphs

By Murray Bourne, 16 Feb 2012

I just added a new page on IntMath.com, Interactive Ellipse Graphs.

There are 3 interactives:

1. The first illustrates the property of ellipses, that they are the "locus of a point where the sum of the distances from 2 fixed points is constant". This is usually quite a confusing statement for first timers.
2. The next shows the effect on an ellipse's equation when moving its center.
3. The final one illustrates what we mean by the eccentricity of an ellipse.

So check it out and let me know what you think. Any suggestions for improvement?

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't mix both types of math entry in your comment.
