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.
- The Newton's Method applet. Approximate
zeros of many functions with this applet.
- 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.
- Another new applet, the ODE
Grapher. This compares the Euler, Improved Euler and Runge-Kutta
methods for solving differential equations numerically. Yum.
- LeastSquaresGrapher
- The raw Least Squares
Grapher allows you to input a set of data points and graph the
least squares line. log-log and semi-log plots are also
available.
- The Tutorial Version is
constructed when you supply a set of data points by passing them as
parameters to the applet. This makes an interactive version in which
students must try and guess the slope and intercept for the
least-squares line.
- RectGrapher
- AreaGrapher
- GraphToy
- PolarApplet
- Parametric Grapher
