ti-89

     

The TI-89 an the TI-89 Titanium are graphing calculators developed by Texas Instruments. They are differentiated from other graphing calculators by their powerful computer algebra system, which allows symbolic manipulation of algebraic expressions. For example, equations can be solved in terms of variables; most other calculators can only give a numeric result.
