Review: Excellent. - Excellent. My son is using this for Calculus. Review: Great Product but backup your self created programs. - Best product ever, Except that the batteries died after a month of usage. I am using eveready alkaline now and lasts more than a year under heavy usage. Also storing self created programs is not useful as the calculator resets some times without prior notice causing the user programs and past calculations to get erased. Does 3-D graphing very well though in that small lcd screen. Using the later colour models in not useful for me as their resolution is not any where near that of the modern phones. And I wouldn’t want to remember another device to hook up every three days to the power outlet. Besides the device will be useless once the rechargeable battery dies. This one though can run a lifetime if maintained properly as it uses disposable akaline batteries. And awesome for quick and dirty calculations when you don’t want a full fledged laptop. ## Features - 2.7 MB ROM memory for data archive and storage of Apps. 188 KB of available RAM memory - Icon desktop that allows easier access to apps and editors - USB port for computer connectivity, unit-to-unit communication with TI-89 Titanium graphing calculators via presentation link adapter - Advanced mathematics software functionality is suitable for college mathematics and engineering coursework - Symbolic manipulation for algebra, calculus and differential equations - Country of Origin: China ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0001EMLZ2 | | Best Sellers Rank | #108,832 in Office Products ( See Top 100 in Office Products ) #22 in Graphing | | Box Contents | .

The apps are either TI study card, or TI notes. Both allow you to create notes on a computer and then transfer the notes to the calculator. **Q: does it come with instrction booklet** A: Yes it does come with a booklet with basic instructions, but if your a student in college I would suggest taking the calculator class, or arranging time with someone who knows how to use it. I can tell you that there is nothing you can do to hurt it. Unlike a computer you can't screw it up, so be brave and push buttons!!! **Q: does this calculator function as a financial calculator as well?** A: Go to TI web page to download the application. Once you install the application, it will function as a financial calculator. **Q: Is it 3d?** A: Yes, it can plot 3D surfaces in the form z=f(x,y) and diferential equations. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent. *by K***R on 31 March 2017* Excellent.
