Beginning of sample modeling tour

This sample tour takes you through the land of ellipses.

Feel free to wander from the tour. At any point, you'll be able to see a statement of the property by clicking on the Statement button. Similarly, you can see a proof, the detective's derivation, exercises, or a critique of the whole process. At any time you can click on the appropriate button and detour to an index page of properties, of term definitions, of problems, or of historical periods.

Tour guides cannot be responsible, however, for your safe return to the tour. You may need to use your browser's Back button a good bit. You can always start over at the Introduction page.

Enjoy your site seeing!
