Jul 19, 2012 The Texas Instruments TI-85 has been designed as a graphing calculator for engineering and calculus students; yet it is versatile enough for other math applications. Designed with students of higher math in mind, the TI-85 is a scientific calculator that offers a wealth of features and functions that will take you smoothly from pre. Featuring several top brands. We provide free PDF manual downloads for several leading Calculator manufacturers, including: Ativa, Canon, Casio, Radio Shack, Sharp, Texas Instruments, - VIEW ALL -. Most Popular Manuals. There are no differences between the TI-60 manufactured in Italy or an US-built TI-60. If you are interested in the calculating accuracy of scientific calculators don't miss the Calculator forensics. Like usual there is a counterpart for financial purposes, don't miss the rare BA-III calculator. The TI-60 is featured in the Texas Instruments Incorporated bulletin CL-899 dated 1986. Page 341 Appendix B: Reference Information This appendix provides supplemental information that may be helpful as you use the TI.85. It includes procedures that may help you correct problems with the calculator, and it describes the service and warranty provided by Texas Instruments.

TI-86, TI-85 The TI-86 is a good choice for a graphing calculator to use while learning from Precalculus. The older TI-85 will do most of the activities presented here, but it lacks some editing and statistical features of the newer model. The biggest improvements in the TI-86 are the increased memory and the ability to load and run assembly.
