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.

## Questions & Answers

**Q: Does this graphing calculator save notes, can it make notes?**
A: Yea, but only with one of two different apps that are and available from TI. 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.

### ⭐⭐⭐⭐⭐ Review
*by E***. on 5 January 2018*

Sehr gutes Gerät; da ich das Vorgängermodell hatte, habe ich mich wieder für den TI-89 entschieden. Einziger Kritikpunkt die Produktbeschreibung stimmt mit dem Lieferumfang nicht ganz überein Lieferumfang lt Beschreibung auf amazon: 4 AAA Batterien => check USB-Kabel für die USB-Schnittstelle => check USB-Kabel für die Verbindung zwischen TI-Rechner und Computer => check Handbuch => leider nein Produkt CD der verfügbaren Software einschließlich der frei erhältlichen Applikationen und der Handbücher als PDF => check Ein physisches Handbuch aus Papier war leider nicht dabei. Desweiteren täuscht das Titelbild (was ich allerdings nicht negativ werte), da das Gerät selbst in einem Karton statt in einer Plastikverpackung kam.
