A collection of seven miscellaneous programs: Grid, Polar Grid (draws rectangular and polar grids resp., then these grids can be projected onto a screen), Trig 1, Trig 2, Trig 3 (graphically demonstrates the definitions of the trig functions), x^n sin(1/x) (animated display of tangent lines to these curves), and Polygons (draws regular polygons in a circle and calculates area and perimeter).
