CalcPlot3D has four built-in explorations which each contain a pre- and post-test. Our current goal is to develop more explorations and to import these explorations into WeBWorK.
The current explorations, which should be accessed with Firefox, Safari, or Internet Explorer (not Chrome) are:
- Dot product (10-15 minutes) focuses on the relationship between the angle between two vectors, the length of the vectors, and the value of the dot product.
- Cross product (15 minutes) guides students to explore the relationship between the angle between two vectors, the length of the vectors, and the cross product direction and length.
- Velocity and acceleration (1 hour) demonstrates the relationship between the velocity, acceleration, and position vectors using a variety of examples.
- Lagrange multipliers (1 hour) reinforces the Lagrange multiplier formula through a series of examples of contour plots of surfaces and constraint curves.
If you are an instructor interested in using an exploration in your class, please contact Paul Seeburger to access your student responses.
