Making a Good Calculator Better

The Texas Instruments TI-Nspire calculators may be the most advanced graphing calculators for math and science classes, but they’re about to get better with a software upgrade. The free program raises the handhelds to version 1.7, which adds a bunch of abilities. On top of being able to customize when the system goes into battery-saving sleep mode, the latest software has application hints that can help teach how to use the calculators. The systems can now create a variety of statistical graphs, students can view data and plots side by side and they can now work with conical sections. The download is 7.8MB.
