Overview
The TI-Nspire CX II CAS is Texas Instruments higher-end graphing calculator, adding a Computer Algebra System and a color touchpad-navigated screen to the graphing and statistics tools found on the TI-84 line, bundled with TI-Nspire student software for PC and Mac.
The CAS engine is the real differentiator: it can manipulate symbolic expressions and abstract algebra rather than only produce numeric results, which is why it is approved for AP and IB Diploma Programme exams that allow a CAS-capable calculator (confirm any specific exam's own rules before relying on this where CAS is restricted). TI includes a 4-year software license and positions it as a starting point for programming, engineering and robotics coursework.
- 3.5 inch 320x240 color display
- Built-in Computer Algebra System
- Touchpad navigation with quick alpha keys
- Includes TI-Nspire CX Student Software
Who it's for
Suits a student in calculus, engineering or a CAS-approved exam track who wants symbolic algebra alongside graphing. Overkill for a student who only needs basic graphing, where a TI-84 Plus CE covers the same core exams for less.
Pros and cons
- Computer Algebra System for symbolic math
- Color screen with touchpad navigation
- Rechargeable battery rated up to two weeks
- Bundled 4-year student software license
- CAS calculators are barred from some exams
- Costs more than a non-CAS TI-84
Performance notes
The 3.5 inch color screen runs at 125 DPI with 16-bit color and offers six graph styles across 15 colors, and the rechargeable battery is rated for up to two weeks per charge. Touchpad navigation and quick alpha keys are meant to speed up entry compared with the button-only layout of older TI models.
