NOTE: These applets should all be stable now. Please let us know of any problems you might have; platform and browser info might be helpful in helping us locate any bugs.
  1. The Newton's Method applet. Approximate zeros of many functions with this applet.
  2. The Taylor Polynomial applet. You can enter a function and see the Taylor Polynomials up to order 20. Because symbolic differentiation can get complicated as we go to higher orders, it is possible to run out of memory unless the applet can rein itself in. This freezes the applet, which is a Bad Thing. So, we keep track of how long each symbolic differentiation takes, and stop the process if the previous calculation took more than 500 milliseconds. This value seems to work OK both on our 480MHz 64-bit Sun and on my 100MHz AMD machine. This explains why some functions will not give 20 Taylor Polynomials.
  3. Another new applet, the ODE Grapher. This compares the Euler, Improved Euler and Runge-Kutta methods for solving differential equations numerically. Yum.
  4. LeastSquaresGrapher
  5. RectGrapher
  6. AreaGrapher
  7. GraphToy
  8. PolarApplet
  9. Parametric Grapher
