Amazon.com Product Description

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-algebra all the way through college calculus. Its data I/O port and unit-to-unit link (compatible with all TI-85 and TI-86 models) allow you to easily transfer your final graphs and equations among systems, while the 28K RAM and customizable menu keys provide quick access to necessary programming functions. As you advance through classes, simply reprogram the keys to keep up with your new textbook chapters.

Functions are widely varied, and include the ability to solve for systems-of-equations, polynomial-root, or any variable in an equation. Graphing possibilities include parametric equations, polar equations, and solutions to differential equations. Statistical analysis runs the gamut from linear, logarithmic, exponential and power to quadratic polynomial, cubic polynomial, and quartic polynomial regressions. In addition, data is viewable as strings, pictures, or vectors. Simultaneous separate graph capability and 15 interactive zoom features are also included.

The display is a generous eight lines long and 21 characters wide; this unit is powered by four AAA batteries, with a dependable long-life lithium ion providing memory backup. Texas Instruments includes a one-year warranty covering parts and service.

What's in the Box
TI-85, lithium backup battery, link cable, guidebook with warranty card, and impact-resistant slide case; AAA batteries not included

1 out of 5 stars That calculator is not the TI85 graphing calculator from Texas Instrument........2006-10-05

Don't get me wrong but that calculator shown in the picture is not the TI-85 graphing calculator from Texas Instrument. I have no idea what that thing shown in the picture is.

1 out of 5 stars The calculator did not work.......2005-09-21

The calculator did not work when I got it even after putting new batteries in it so I contacted Mr. Carlson. He was so nice and got right back with me. He apoligized for it not working and said that he would return my money. And in a few short days, I got a check in the mail from him. I found him to be a very nice guy and very true to his word.

4 out of 5 stars replaced my TI-30 Stat.......2003-09-10

I used a scientic calulator for years. I bought the TI-85 my Senior year of High School and even though I'm not yet in college (five years later) I'm still a nerd that likes to play on it. most of time I just use it for basic stuff I can still do with a new TI-30X I bought granted I can graph with it and I've been looking hard at TI-89 for no other reason than I can. (more than likely would be my next purchase if I did buy another one) the sad thing is resources for this calulator are limited seeing as it's been discontinued but you know it's still more powerful with it's computing power over my GF TI-83 plus. it just lacks the storage of memory.

5 out of 5 stars Excellent Investment.........2003-03-25

Its an excellent investment for engineers. The Calci helps a lot in mathematical calculations. It has a Huge number of engineering applications. Few applications which I found VERY Useful are

(1) Inverse of a Matrix (2) Solving Quadratic and higher order Equations. (3) Plotting the graph of Algebric Equations which help in finding out the Maxima and Minina..

4 out of 5 stars TI - 85 Overall, a good graphing calculator........2003-01-19

With a large number of features and a huge range of functions, the TI-85 is a graphing tool that is well worth its cost. It is fully programmable, using a BASIC-like programming language. Texas Instruments discontinued this line of calculators however, and though they may have had their own reasons, I know of at least two flaws with this particular calculator. The first is that there are some bugs in its programming, such as its inability to convert negative temperatures. The second and much more serious problem is that the screen is not reliable. Roughly half of these calculators have one or more lines or columns of pixels fail after a few years of use. As long as you aren't paying retail price, however, the $$$it might cost for a used TI-85 is more than worth it. Enjoy.
