At today's meeting, Dr. Heath and I have decided to develop a Java applet which can graph the solution of Ax = b for a 2x2 system. We have also planned development for an online activity which will lead a student through the steps of Gaussian Elimination.

Date: November 8, 2000

Meeting cancelled. Development continuing on Ax = b Java Grapher.

Today, Dr. Heath and I met and discussed how to fix special case errors found in testing the Quadratic Formula Activity.  Previously, the java applet did not properly handle negative discriminants when computing square roots.  Dr. Heath provided formulas for fixing this, which I will be working on implementing in the next week.

After this, we examined the progress of the Ax=b graphing applet.
