Customer reviews for Texas Instruments TI-85 Advanced Graphing Scientific Calculator
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.

Texas Instruments TI-85 Advanced Graphing Scientific Calculator:: 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.
