A Collection of Tools for Multivariable Calculus

The mathlets presented here provide user-friendly tools for visualizing and manipulating basic objects of multivariable calculus: parametric surfaces in rectangular, spherical and cylindrical coordinates, parametric curves, and graphs of functions of two variables. The user can enter his or her expressions using familiar graphing calculator syntax. The mathlets will plot the corresponding surface or curve which then can be rotated in real time. One of the mathlets is devoted to exploring spherical coordinates which are often hard for students to visualize. All mathlets contain a variety of examples and practice problems.

Suggested Uses:

  • For independent exploration by students;
  • For discussions with students in smaller groups in a laboratory setting;
  • For classroom demonstrations with a computer projector.
