TI-Nspire CX CAS

I have been using this calculator for about six weeks. I am not sure if the TI Nspire CX CAS (TI-N) was meant to replace the TI-89 Titanium, but a few minutes with the TI-N will most likely make you suspicious of a coup d'etat. To start with, the TI-89 is a great graphing calculator with many capabilities, to include programing. Unfortunately, its owner's guide does not do it justice. Although, from the looks of the owner's guide from the TI-N, one would come to the conclusion that that Texas Instrument either expects their clients to be genius, or they don't care about putting a bit more effort in their products. The TI-89 has been in the market since on or about 2004. The last update to its software was on or about 2005. It's connectivity computer software is outdated, and good look trying to get it to work with a Mac. I tried numerous time to communicate with Texas Instruments, but to the end of no positive results. You don't have to take my word for it. Just do a search about the TI-89 and its Mac connectivity software and the results will speak for themselves. On the other hand, the TI-N is about the same size as the TI-89, maybe a cm wider and taller. It is thinner and it weights a bit less. Its color screen makes it much more easier on the eyes, especially when doing homework late at night. The menu is almost as the same as the TI-89, which makes it easier for those that wish to make the transition to the TI-N. Three-D graphing is very simple and and quicker than the TI-89. As I implied in my previous comments, don't expect much from the owner's guide, but YouTub has plenty of videos that will help you get around of many of the TI-N capabilities. Additionally, many of the online videos will take the time to compare the the TI-89 and the TI-N. If you are a TI-89 user looking to make a transition, you will find that it is not that complicated. Making a purchase of the TI-N can present some challenges, since it is a fairly new calculator. Maybe by the time you read this that maybe something of the past. Still, many stores offer the chance to place orders, which it takes about a week for you to get your hands on the new calculator. Since I order mine through Amazon, it only took 2 days (of course that I had to pay the extra fees for express delivery). For Mac users, you will find that the included connectivity software works great-lets just hope that Texas Instruments keeps it updated. You do not need the software to get the calculator working. Although, there is a new operating system and I am not sure that it is possible to make the upgrade without the connectivity software. One item that I think TI could have done better, and it is a mystery since many digital input devices have transitioned to it, is the inclusion of a qwertey keyboard layout. Still it is a bit better than the TI-89's keyboard because every letter has its own key, which you don't have to depend on pressing the 2nd key followed by the letter. Again, you don't have to take my word for it. Just make a web search and you will find many good comments about the TI-N. Thank for taking the time to read my comments.

I bought this calculator for an online college algebra course. I originally got the TI-Nspire CX, but within about 5 minutes I knew I wanted the CAS feature. The return process with Amazon was awesome and I was very happy with the CAS version. I had debated prior to ordering, but not knowing much about math, I wasn't sure if it would be worth it. Now having just completed the semester, it is completely worth it and then some- here is why: 1) some problems you have to work in college algebra will have two or more answers. Without the CAS version, only one answer is displayed and there is no indication that other answers exist. With the CAS version, the applicable answers are displayed. 2) With CAS, the calculator can do more difficult math calculations. If you're a math wiz anyway, this probably isn't that big of a deal. Personally, I loathe math, put it off for as long as possible, literally the last class I needed for my degree. Getting this calculator was a game changer, I just wanted to get through the course. Sure, I learned along the way but if the calculator can do the heavy lifting, then I feel it should. Once I learned how to use this calculator, it was a matter of entering the equations into the calculator, pressing enter, and writing down the answer. Quadratic equations became almost as easy as figuring 2+2. As a side note, I just looked on the SAT approved calculator list and this is currently on it, so I don't know why anyone would buy a different graphing calculator unless this advanced level of a calculator isn't allowed in your test. With each week's homework assignment I found more the calculator can do- there are tons of demo videos on youtube that were helpful. Then the day before my final, I stumbled on to what may be the coolest feature of the calculator which is the way programs can be written. You don't have to be a programmer, just download some of these to the calculator, it is very easy using the supplied software. I downloaded programs to find the slope and solve quadratic equations and suddenly I didn't have to memorize equations any more. The great thing is you can use it for these sort of things as little or as much as you want- personally I opt for having the calculator do as much math as possible. The student software that comes with it is very handy if you have dual monitors, basically it is a calculator emulator and does everything the calculator does on your computer. I could enter things in much more easily with my computer keyboard than the tiny keys on the calculator so I used the software for homework and the calculator for my tests. Finally, I would say the proof that this calculator is worth the cost is to imagine how much I disliked algebra before this semester in comparison to my final grade for college algebra from my university which was just over a 99%.

Fit for my purpose.

日本語の取扱い説明書は、一関工業高等専門学校 名誉教授 梅野善雄先生が 執筆された414ページのものをダウンロードして勉強中です。 無限の可能性を感じます。 小さいけれど強力な数学コンピューターです。 また、(x^2-5)を2から8まで数値積分するのに シャープのEL-509Jでは、4秒かかっていましたが、 TI Nspire CX CASでは、瞬時で計算します。 脅威の計算速度を持つグラフ電卓です。 昔、Windows PC用のMathCadを買って少し遊びましたが、このグラフ 電卓を使いこなせば、基本的な部分は代替出来るような気がします。 Amazon.comのこのグラフ電卓に関するレビューが2000以上もあり、 相当な数の学生や技術者が使い込んでいると推測できます。

This is probably the best graphing calculator you can get. Great for secondary students learning Pre-Calc and functions and university student studying engineering, science, and math. It’s allowed on tests like the SAT and AP. Colour screen, computer software included. Scratchpad and multiple applications are installed in this calculator. It’s equipped with a full 26-letter keypad but not in QWERTY order. Programmable and responsive. Capable of doing geometrical transformations, algebra, statistics, and calculus. CAS-enabled and financial functions are built-in for easy-use. The handheld comes with a charging cable, a USB cable, quick guide, and software license. This simply does everything you would ever a calculator to be able to do and won’t disappoint you. If you are looking for a powerful calculator and are going to use it for a long time in the future, this would be the right choice for you.

Perfect. Even arrived a day early.

Esta es la segunda calculadora que compro de este modelo. Es excelente y muy cómoda de usar. No uso el trackpad, porque me parece algo innecesario para una calculadora, pero la batería dura de 2 a 3 semanas, se carga con cable mini-USB y sirve MUCHÍSIMO en clases de universidad con Integrales complicadas y métodos numéricos.
