MATH TOOLS NEWSLETTER - OCTOBER 2, 2004 - No. 19 At the end of September we added several new features. Each individual resource page now identifies the resource's language and cost, if any. It will take a little time to edit the resources already in Math Tools but we're working on it. In fact, we could use your help! If you notice a resource that should be marked as a commercial resource, please let us know. We've also added a number of new Technology Types, so our full list now includes: Calculator Texas Instruments Computer Cabri Computer Algebra Systems Mathematica Fathom Flash Java Applet JavaScript Presentation software PowerPoint Shockwave Sketchpad Spreadsheet Excel PDA Palm OS PocketPC If you have tools that you can suggest for any of the courses, feel free to tell us about them.
