### Animation: Values of Tangent Requires Geometer's Sketchpad (download Sketchpad without purchasing it to view this document)

The values of the tangent function as the terminal side rotates counterclockwise

### Conic Sections

 Ellipse: Sum of distances from the foci is constant (182K)

 Conic Sections Defined by Eccentricity Java Sketchpad version (Java enabled browser required) Geometer's Sketchpad version (GSP 4 required) Conic Sections Defined by Eccentricity 1. Move the slider for eccentricity and see what kind of conic section you get. 2. Move the focus to see what impact that has on the figure. 3. Move a point on the directrix to show that no matter what point is taken on the curve, the ratio of the distance to the focus over the distance to the directrix always equals the eccentricity.

### Parallel Cross-Section Figures

 Equilateral Triangles (363K) Squares (366K) Squares (on diagonal) (331K) Circles (1.9M)
