1 – Texas Instruments TI NSPIRE CX CAS Black Slide Cover

Top Reviews Careful Shoppers! This cover comes with the TI Nspire CX CAS. None of the photos or descriptions mention it. As designed, it fits on the back, which is how it is packaged by TI. If you lost yours, it is OEM quality; otherwise you will end up dealing with the return for duplication. . I lost my Ti-Nspire CX case cover during my year at school. You don’t realize how important the case is until you realized that your calculator was on in your backpack the whole day, draining the battery significantly. So for anyone who is having doubts or having trouble finding the right case, this cover is perfect. It slides on perfectly well and has no issues at all. . fits perfect and works like it should . I bought this before I discovered the hand held device came with its own. However backup is always good especially for this hand held device. Read more

2 – TEXAS INSTRUMENTS Instruments GRAFIKRECHNER TI-NSPIRE CX-II T CAS

Top Reviews Tja, was soll man sagen: fÃ¼r knapp 150 Euro erhÃ¤lt man einen Taschenrechner, den man im Prinzip auf dem iPad umsonst erhÃ¤lt :-)Einziger Grund ihn zu kaufen: als Lehrer oder SchÃ¼ler muss man ihn haben. Aufgrund des desolaten deutschen Bildungssystems (planloses KleinKlein in 16 BundeslÃ¤ndern) werden vermutlich auch in den nÃ¤chsten 50 Jahren zu jedem Schuljahresbeginn bei TI die Sektkorken knallen 🙂 . My version of the keypad is red on black, and is of very poor contrast.Equally bad is that the key clicks are like old TI wedgy 1980’s-style hard-click keys which are (a) uncomfortable, and, (b) not as easy to use as fast as other quality keypads such as almost any other calculator on the market, including the TI-83, TI-84,TI-89/Voyage 200, any Casio, any Sharp calculators, even if you get past the unintuitive lay-out.It took me very little time to be able to fly through the menus on the TI-83, and find special characters on the Voyage200, but I am finding it hard to quickly find certain items on the nSpire *unless I use them frequently*.The mouse’pad’ is awful.The functionality of this machine is exceptional but is let down by the keypad both mechanically, and in soft functionality.Thumbs up for the inclusion of student software which is basically an emulator for your PC, although it also includes pairing software so you can start work on your calculator, and carry on on the PC, and vice versa.Come on TI, fire the senior person who made the decision on the keypad ( not the engineers ), get your act together before you lose your reputation. I’m thinking of Casio or Sharp next time unless TI sort out the basics. The TI-83/84 and TI-89 are preferable machines to this, especially the TI-89 which has great CAS. Few people need the extra speed of the nSpire over the nice-to-useness of the 83/4 or 89. There are a few functions unique to the nSpire, but my bet is anyone who needs that extra functionality would be in a position to add a quick program or function of their own to do it anyway.For students, get yourself a T89 which has CAS. I guarantee you will learn maths quicker and easier than the nSpire. If you can find one and afford it, the Voyage200 is a qwerty version of the 89 with a few tweaks to the menu system, but they are very similar. Even though the screens are older LCD so not as clear, you would never regret having one of these machines, but might regret buying an nSpire.If you definitely are against CAS ( why would you,?), then get an 84 or 83.The older machines are easier to play with maths on imo . The best calculator ever. More user friendly than the HP prime calculator despite the fact that it doesn’t have touch screen. A must have tool if you’re enrolled in university level calculus course. . Still learning all the functions but very impressed so far. Battery life is difficult to comment upon as it is so new but seems to be holding up fine. And having Li Ion battery helps enormously. Read more

3 – TI-Nspire CAS Graphing Calculator

Top Reviews I’m an older SW engineer (I graduated college in the early 1980’s). I’ve always been biased toward TI calculators (from my first TI-59 in high school – which replaced a slide rule). I bought a TI-92 in the 90’s when it wore out I bought a TI-89. Now it’s time to buy another calculator so I decided to give a N-Spire CAS a shot.My out-of-box experience wasn’t great. I had trouble seeing (let alone navigating) the screen even with glasses on. After seriously considering returning the calculator, I decided to load the software that came with it as a last effort to help figure it out. I loaded and ran the TI-Nspire CAS software and it suggested upgrading the firmware. After the upgrade I’m much happier with the calculator (especially after setting the font to the largest size).Pros:* Very easy to use (after the firmware upgrade).* Support for multiple font sizes (especially a large font).* Much easier to pickup and just use than my TI-89. Though I loved that older calculator, but I always had to have the manual nearby to remember how to do things I did infrequently. I doubt that will be needed with this calculator. It really is much more intuitive.* I love the CAS features. This saves me a lot of time when writing software because I frequently isolate variables or do calculations that I would otherwise have to work out in MathCAD. Having a calculator that can do this is just more productive for me (and it means I don’t have to deal with the draconian licensing imposed by MathCAD).Cons:* The keyboard is unbelievably bad. Clearly the designers don’t use their product (or they’re 20 years old with excellent eye sight).* My eye sight isn’t that bad – I only need glasses for reading, but I even with large fonts I have to use my glasses because the keyboard has microscopic characters on the green keys and the large fonts are still not large enough.* As learned to use it, I tried several test functions using the CAS features. A couple of the fringe problems gave answers that were different than the TI-89. That doesn’t fill me with confidence, but most of the test functions gave correct answers. But at this point I don’t have 100% confidence in the CAS system. I’ll get a better feeling for this after more use.This calculator is with out a doubt much easier to use. It will probably be a worthy replacement for my old TI-89. But I’m still a bit nervous about the differences in responses between the N-Spire and TI-89. . For most of my highschool career, I managed to make it by on my ti-83 plus calculator. It did what I needed, graphed functions, found sin and cosine, and was more useful than just a regular scientific calculator.Enter Calculus.For the first time in my life, I had a 70% in a class, figuring out derivatives was a chore, and Integrals weren’t any easier. So I bought the Ti-Nspire CAS and boy was I amazed! It can solve derivatives, limits, algebraic functions, statistics, and much more. The pretty font is a huge upgrade over the ti 83, and for the price you just can’t beat this calculator.The only cons are that there is a slight learning curve on the ti-nspire; I recommend that you find a manual and learn the hotkeys for this calculator.For those currently in algebra, trig, and ESPECIALLY calculus I would highly recommend getting this calculator and watch your grades skyrocket. . I purchased this calculator for my son to replace another TI-Nspire that had decided to go on permanent vacation just past it’s one year warranty. The previous calculator did not include the CAS option, so this model seemed to be a nice upgrade. On the page for this calculator was shown the touchpad keyboard and the Dummies book as items often purchased together, so I thought that made sense. The previous TI-Nspire had two keyboards that could be switched out, so it seemed to make sense that this one could do that as well. If you have that same thought, let me dispel it for you. This calculator has a fixed keyboard that cannot be swapped. In fact, the back of this calculator is completely different than the previous calculator. The manual that comes with this calculator provides instructions for removing the keyboard, but upon closer inspection, it is not this calculator. Even though the manual (and I’m not talking about the Dummies book here) references the CAS calculator, none of the images show it or refer to the differences between it and what may be the standard Nspire with a replaceable keyboard. Seems like someone at TI didn’t consider that this model differed from the others. And, since Amazon shows the extra keyboard as something often purchased together with this calculator, it would seem there are others like me who think that is a worthwhile option. If you want this CAS calculator, save your money and skip the extra keyboard. That may be noted somewhere in the description of this item, but I managed to miss it if that is the case.As far as the calculator itself, it does seem to be a very nifty device. My son (a high school sophomore) compares it favorably to his previous Nspire and likes the CAS option. However, in fear that this device will barely make it past the 1-year warranty, I opted for the extended 3-year 3rd party warranty. . The calculator came to my door with the latest OS installed. That was definitely a plus not having to upgrade the firmware straight away. The sheer bulk of the unit, screen size, & resolution were what surprised me initially. So far as I can tell, it does everything my ’89 had done and then some.It’s a great tool, but I have a few moans and complaints: Firstly, the viewing angle on is pretty narrow to get a sharp image, regardless of device setting; there’s ghosting reflection in the screen glass that becomes semi-annoying beyond about 45 degrees. Secondly, my screen is cocked counterclockwise a few degrees. Not a deal-breaker, but it looks out of place. Lastly, you have to do a vertical peck at the keys due to the raised letters and symbols littered throughout the keypad.All in all, for 60 bucks and whatever you find under the sofa cushions, Its a great buy. Once you get past the cross-trainer color scheme and learn the menus, split screen functions, and various other hidden gems, it stands to be the most graphing calculator per dollar spent on the market today. Oh, and I’m not talking dollars per ounce. 🙂 Read more
