Texas Instruments(テキサス・インスツルメンツ) TI-Nspire CX II CAS カラーグラフ計算機 学生用ソフトウェア付き(PC/Mac)

Texas Instruments TI Nspire CX II CAS グラフ電卓がやっと届いた。 主な特徴を列挙すると、 ・速度が約2.5倍に高速化された(Webinar: Introducing TI Nspire CX II Technologyで紹介)。 ・TI BASICにDrawメニューが追加され、基本図形(DrawLine, DrawCircle, DrawRectなど)の描画や着色(SetColor, FillCircle, FillRectなど)ができるようになり、ゲームやアニメ的なプログラムが作りやすくなった。 ・グラフ軌跡のアニメーション的描画機能の追加 ・グラフ係数の動的変更機能の追加 などなど。 また、アイコンなどの画面要素がiPhoneのようなフラットイメージに変更された。 他は従来と互換性があり、違和感なく使える。 ソフトやマニュアル類の最新バージョンが2019.8.14でぎりぎりまで確認作業をしていたのではないかと思う。 CAS(Computer Algorithm System: 数式処理システム)により、因数分解、不定積分、テイラー展開などが可能であり、CASなしグラフ電卓に比べて高価格となっている。 不満は、TI Computer Link SoftwareでTI Nspire CX II CAS グラフ電卓が検出されないこと。PCでの電卓の画面キャプチャは、Student Softwareでできる。

パッケージもきれいな状態で届きましたが、バッテリーが不良品のようで充電できず使えませんでした。 配送などの対応に問題はありませんでした。

Produto de excelente qualidade.

Just what’s you’d expect it to do

The Texas Instruments TI-Nspire CX II CAS is an outstanding graphing calculator that has truly enhanced my learning and problem-solving experience. The vibrant color display makes graphs and charts easy to read and interpret, while the powerful CAS functionality allows for advanced algebraic and calculus computations right at my fingertips. The included student software for PC and Mac is a fantastic bonus, providing a seamless way to explore concepts and complete assignments both on and offline. The calculator’s intuitive interface and responsive buttons make navigation smooth and user-friendly, even during complex calculations. I highly recommend this calculator for students and professionals who need a reliable, feature-rich tool for math and science courses. It’s definitely worth the investment!

Great calculator, it arrived quickly and the packaging was not one of those nearly impossible to open so first impressions were good. The calculator feels light which I am not a big fan of, but I generally baby my calculators so it won't be an issue. I am a professional, not a student, and I have similar calculators. I am not the biggest fan of the document-like approach for the calculator, and I'd rather have some of the more used functions with an assigned button rather than accessing them with menus (even trig functions) rather than the dedicated keypads with all letters. The calculator is very fast and responsive, but the touchpad is slightly annoying to use. I also have the HP Prime, it's direct competitor in terms of features, and so far I enjoy the Prime a bit better; but I like the vector handling of the CX II better than the Prime, so I have both at my desk. The battery life is good, but I honestly wish I could also use conventional batteries like the older TI Nspire (non CX) did, to ensure this calculator will last me a lifetime (I still have both an HP 50G and a TI 89 Titanium purchased in 2005 and 2006 I believe, both working great). Considering the TI 84 Plus CE is at this price range, I think the price of this calculator is very competitive. I'd recommend it over the TI 84 Plus CE, but not ovet the HP Prime. Eventually I plan to install KhiCAS on it, and see if I like it better, but as far as I know it's the 2nd best modern calculator out there, but this is subjective as I have seen people who love the document-like setup and the menus and cleaner looks vs a more conventional look. I will update this review after a few more months of usage

I bought this for my husband while he was in college for Mechanical Engineering. It has a lot of great features. The functions can be a little confusing at first if you have never used this type of calculator before, but the instruction manual is helpful with navigating its functions and capabilities, along with YouTube videos. The accuracy of it is spot on. The adjustable brightness is convenient, especially for late night study sessions or homework procrastination. It is pretty lightweight considering that it is a graphing calculator. For comparison, it is not significantly heavier than any of the other Texas instrument calculators. The price is definitely fair in comparison to other graphing calculators, and it is worth it for this one considering its durability and purpose.
