## Description

Product description               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.                  .com               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.

## Questions & Answers

**Q: why can't I find a TI-85 scientific calculator brand new somebody help me please**
A: Hi, the TI-85 was replaced by the TI-86, which is also discontinued. I have a TI-85 and a TI-83 plus for sale on Amazon.  In my opinion as a Math Prof., the TI-83 plus is just as good or better.  Just my opinion.

**Q: Does the calculator have the rref function?**
A: Yes, it does have the rref function for matrices.

**Q: how is the viewing screen. any flaws**
A: I have noticed I continually have to turn the contrast up even though I never turn it down.  Maybe it's the heat where I'm at (I notice I have to do it more when I've kept the calculator in my car during summer months) or some other outside cause but once the contrast is turned up I am able to view everything on the screen just fine.

**Q: Hi! Can the calculator perform large factorials like 365! ? Thanks.**
A: Yes. The factorial operator is under PROB, which is under MATH.
