The TI-89 Titanium lets you perform basic math, algebra, calculus, graphs, matrices, and statistical functions and creating animations, graphing 3-D rotations, and plotting contours. Graphing functions include basic function graphing, parametric graphing, polar graphing, sequence graphing, 3-D graphing, and differential-equation graphing. Additionally, the TI-89 Titanium includes symbolic manipulation, constants and measurement units, statistics and data plots, a numeric solver, a text editor, programming capabilities, tables, a split-screen function, variable management, and the ability to link to other calculators or a computer. The TI-89 Titanium's flash technology allows upgrading to future software versions without having to continually invest in new calculators. The 188 KB of RAM, combined with an impressive 2.7 MB of flash memory (three times the memory of the TI-89), are more than sufficient for stored functions, programs, and data, and add welcome speed to go with the TI's reliability. Create custom menus or use the default menu. Another feature is the Program Editor, which gives you the ability to write custom applications. The large LCD is adjustable to your environment and can be viewed clearly under a variety of lighting conditions. The calculator also comes with an input/output port and cable, letting to synch up with other TI-89s or TI-92s, as well as a USB port and cable. An attached, hard slide cover protects the calculator.
Amazon.com Product Description This advanced graphing calculator is packed with more features than you might know how to use. The TI-89 Titanium lets you perform the expected functions of an advanced model--basic math, algebra, calculus, graphs, matrices, and statistical functions--and do cool stuff like creating animations, graphing 3-D rotations, and plotting contours. Graphing functions include basic function graphing, parametric graphing, polar graphing, sequence graphing, 3-D graphing, and differential-equation graphing.

The only negative I can think to mention is that TI could have done a better job alerting the user about the battery getting low. I use the calculator a lot--at least a few hours each day--and when it dies it simply shuts off. In each instance I have been given zero warning, the screen just suddenly went blank. If you rely on this calculator keep a spare set of batteries in your bag at all times.
Functions: It provides multiple functions such as calculus, finance and statistics, etc. You can access different functions in easy way. You can obtain various forms of answer as you need. For example, in mathematic field, you can select to get answer form as numerical, matrix and liner algebra when you enter simple numerical equation. For finance field, you can use its program to get rate of interest, NPV easily. You can use it in simple way whatever you study in finance, engineering or statistics. It has covered all the functions you desire as a calculator.
Quality: It seems a little expensive than other calculators and some people choose another due to price consideration. But if you own it, you will know the benefit you get more than money. It does not have any malfunction since I owned it about four years ago. It was fell to floor several times and nothing happen. The clear screen with comprehensive steps also offer you opportunity to see how you go through your questions previously.
Convenience: I intended to studied engineering before and I took calculus class. Ti-89 provided me the way to test my answers with matrix, graph and integral. I changed my mind to study finance finally and it required financial calculator. I took statistics class at the same time and Ti-89 was useful in that class. I discovered Ti-89 also has finance function so I do not need buy new calculator and bring those together every day. Every time you want to do calculation, Ti-89 can satisfy all you need and you do not need seek another.
Ti-89 is a product that gather wisdom of Ti-89 to satisfy the daily use. You can obtain impeccable function, good quality and convenience with one-time payment. It will define help you with study and career and you cannot miss that.

Remember, maths theory doesn't age but calculators do, the ti89t is based the mc68k processor, which is one of the best cpu's ever produced, given it's date of intro., 1979 it is a little slow but if you are a tolerant person then speed is not such a big deal.The inspire build is no where near, as robust as, the ti89t is.
Il prodotto (una Ti 89 Titanium) è arrivato il giorno 27 giugno, adeguatamente imballato, è stato spedito dall'america.
Secondo il tracking il pacco è stato spedito utilizzando DHL dall'america, quindi è arrivato in Italia dove è stato bloccato in dogana per circa 10-15 giorni, da li è stato spedito utilizzando la posta ordinaria ed è stato consegnato.
La descrizione diceva "usato in ottime condizioni" ed effettivamente è proprio così, la calcolatrice è immacolata, presenta segni di usura quasi impercettibili, non presenta graffi sulla cover e sono presenti ancora i gommini sulla custodia/calcolatrice, è pulitissima ed i tasti non sono sbiaditi/usurati, il display è perfetto ed è difficile distinguerla da un prodotto nuovo.
è arrivata solamente la calcolatrice, senza batterie (servono 4 ministilo per farla funzionare), senza cavo (che comunque non è una gran perdita visto che basta un qualunque cavo miniusb) come chiaramente indicato quando ho fatto l'ordine.
Per quanto riguarda il prezzo, la cosa che mi ha fatto storcere il naso è che al momento dell'ordine ho pagato in totale 74,98 euro (cioè 68,27 euro per la calcolatrice e 6,71 di spedizione). Pensavo che la spedizione comprendesse anche la dogana, ma in realtà quando mi è stato consegnato il prodotto ho dovuto pagare al postino 18,92 euro di costi di dogana (quindi in realtà ho pagato complessivamente circa 94 euro).
Nonostante questo il mio giudizio è complessivamente positivo sul prodotto e il costo, anche se aumentato dalla dogana è comunque inferiore al prezzo che avrei pagato acquistandola nuova a 200+ euro.
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.
Consigliata per studi universitari di matematica fisica ingegneria.
Il prodotto si presenta all'interno di un pacchetto, avvolto in carta-bolle; senza cavi, batterie ed imballo originale.
Erano presenti tracce di adesivo sulla cover.
Molto meno buona la transazione. Ho pagato subito all'acquisto ma il prodotto non era disponibile nonostante le indicazioni sul sito dicessero il contrario. Ho dovuto aspettare 5 settimane per averlo.
Non mi piace trattare con chi non da informazioni precise
