Push APPS, choose data/matrix, 3. New, pick any variable, enter on the table for your x and y data under c1 and c2 if you are doing quadratic regression per se. When you are ready for regression, push F5: Calc, and pick your regression type, set x... to c1, and y... to c2 per your table's field names, change Store RegEQ to ... y1(x) or y2(x) or whatever you would like to use from the drop down menu. When you are ready to process your data into a regression, press ENTER. The next window will show your coefficient values. **Q: Can this calculator do gamma integration and integration of beta functons.** A: Yes **Q: I need a ti84 for my statistics class. Would this one work or just confuse me more.. ?** A: You could ask the instructor if the TI 89 would work ok for your class. Some classes are highly focused on instructions for a particular calculator and others are not. The instructor could tell you so. The TI 89 will work fine for statistics. If the TI 84 is recommended for your course, that may be a better purchase cost wise and if the extra functions may make it more confusing to use. On the other hand, if you value having more features and can zero in on the ones you need, this may be a better buy than having to buy yet another calculator for a class recommending a higher level calculator. **Q: What does it mean that it's programmable and what are the benefits of that over the standard ti89? My son needs this for college.** A: it means that you can actually program a function or a formula on to the calculator, my personally would not recommend the ti89 titanium calculator until you son is taking calc III, due to the fact that is no useful in calc I and II, because that's only dealing with 2 variable functions, I have it and didn't get fully usage until I taking calc III and general physics. TI84 is the way to go with.... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Calculator *by A***R on 1 May 2024* Great item ### ⭐⭐⭐ Review *by R***T on 5 February 2020* I ordered ti-89 but I got tI-89 .I paid 1036 aed but I saw the price of TI-89 is 758 aed ..bit consfued. ### ⭐⭐⭐⭐⭐ Review *by I***S on 23 March 2025* The TI-89 Titanium is one of the few hand-held real-computers, that one, apart from using it as a programmable super calculator, can also use it as a unique teaching aid for getting deep into the superior MS68000 CISC ISA Technology, that only by foolish historical accidents did not prevail over the inferior, by any metric, intel x86 architecture. One can directly code in MC698000 assembly for/on this amazing calculator and do real-magic. You'd only need "TI Connect" software, {not TI Connect CE} and some books available on amazon and/or on free legendary technology's book repositories like 'internet archive'. ## Frequently Bought Together - Texas Instrument Ti 89 Titanium Programmable Graphing Calculator - TI-89 Graphing Calculator For Dummies - Texas Instruments TI-89 Titanium Graphing Calculator (packaging may differ) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/49351184-texas-instruments-ti-89-titanium-graphic-calculator](https://www.desertcart.hr/products/49351184-texas-instruments-ti-89-titanium-graphic-calculator) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-27*
