Ti 85 Graphing Calculator Review
The TI-85 graphing calculator was created by Texas Instruments in 1992, their second graphing calculator (the first graphing calculator was the TI-81).
A significant improvement compared to the TI-81, the TI-85 was created as an engineering and calculus calculator, for use in courses that teach engineering and calculus. This calculator included BASIC to allow programming.
The TI-85 has the ability to connect to other calculators using a three-conductor cable. By using the TI-Graph Link cable and the necessary software, it is possible to connect the TI-85 to a personal computer as well.
