CBL 2™ Program for the TI-89 Titanium

This activity provides a program that can be used when the TI-89

Titanium is connected to a Calculator-Based Laboratory™ (CBL 2™) unit.

This program works with the “Newton’s Law of Cooling” experiment,

and is similar to the “Coffee To Go” experiment in the CBL System

Experiment Workbook. You can use your computer keyboard to type

lengthy text and then use TI Connect™ software to send it to the

calculator. More CBL 2™ programs are available from the TI Web site at

educaton.ti.com.
