Mathematics
Here you can find a series of tutorials and worksheets I created using The Geometer's Sketchpad and GeoGebra.
Music:
| Link | Musical chord and scale calculator: An interactive diagram depicting musical intervals, chords and scales and component elements. |
| Link | Frequency Doubling: A description of how the frequency of musical tones double as the number of octaves increases. |
Art:
| Link | Color cube: A demonstration of the different color components used to create images on your computer monitor. |
| Link | Sri Yantra: The Sri Yantra mandala. |
Astronomy:
| Link | Geodetic Latitude: A description of geodetic latitude and its relationship to the Earth's surface. Also discusses "circles of latitude". |
| Download | Planetarium: An animation showing the eight major planets of the solar system orbiting the sun. |
Conic sections:
| Link | Bezier / Parabola: A demonstration showing that a Bezier curve is also a parabolic segment. |
| Link | Parabola Construction: A demonstration showing how to trace a parabola. |
| Link | Ellipse & Hyperbola Construction: A demonstration showing two methods of constructing the ellipse and hyperbola geometrically. |
| Download | Ellipse from center and axes: A GeoGebra tool for creating ellipses from a center point and two axes. |
| Download | Ellipse from center, segment and point: A GeoGebra tool for creating ellipses form a center point, a segment and a point on that segment. |
| Download | Hyperbola from center, segment and point: A GeoGebra tool for creating hyperbolas from a center point, a segment and a point on that segment. |
| Download | Parabola from vertex and focus: A GeoGebra tool for creating parabolas from the vertex and focus. |
| Download | Ellipse from two points and eccentricity: A GeoGebra tool for creating ellipses from a center point, a vertex and an eccentricity value. |
Other curves:
| Link | Beta Distributions: A great class of curves for generating smooth random distributions with known limits. |
| Link | Quadratic Bezier Curve Construction: A demonstration showing how to construct a quadratic Bezier curve geometrically. |

Surfaces:
|
Link |
Parametric sphere with Euler rotations: A demonstration showing how to plot three-dimensional curves in GeoGebra and apply Euler rotation matrices to them. Curves are not drawn in perspective however. |
|
Link |
Metaballs: A description of different techniques used to create the class of surfaces known as metaballs or "blobs". |
