The Texas Instruments TI-Nspire CX II CAS Go to product viewer dialog for this item.
The operating system relies on "Documents" (like a mini-Notebook). You have tabs for:
: To define a variable, type its name, use the := operator, and assign it a value. For example, a:=5 defines a as 5. You can then use a in calculations.
But he didn’t turn it off. He couldn’t. The next day, he powered it up for a quiz on arc length. The first problem: Find the length of y = x^(3/2) from x=0 to x=4. ti cx ii cas
: It uses a menu-driven, computer-like interface with a touchpad and a high-resolution backlit color display, making it easier to visualize complex 3D functions and data plots.
The TI-Nspire CX II CAS is not just a calculator; it is a handheld mathematics laboratory. Texas Instruments organized the interface around dynamic "Apps" that share data seamlessly.
It features a faster processor than the original CX CAS, resulting in quicker boot times and more responsive graph panning. One test showed it completing a complex computation in 6.4 seconds , compared to 14.4 seconds on the older model. The Texas Instruments TI-Nspire CX II CAS Go
Educators can temporarily disable the CAS functionality or other specific tools for testing environments where algebraic manipulation is not permitted.
| Pros | Cons | | :--- | :--- | | is a lifesaver for checking calculus/algebra. | Expensive (~$150-$180). | | 3D Graphing is impressive and useful for multivariable calc. | Steep learning curve ; the menu system is not intuitive at first. | | Battery lasts forever (weeks, not hours). | Prohibited on the ACT and many non-AP exams. | | Python coding built-in. | Touchpad can be finicky for precise mouse movement. |
