![]() The practical use of both versions extends far beyond education, which is a great sticking point for those who want to pursue math, engineering, or other math-heavy career paths. "The TI-NSpire CX CAS graphing calculator provides the algebraic capability to symbolically solve equations, factor and expand variable expressions, complete the square, find antiderivatives, computer limits, and exact solutions in irrational forms, making it a robust hands-learning tool that satisfies math and science curriculum needs from middle school through college." The CX II can perform a lot of math tasks and lends itself to use in other fields. This also adds a level of sophistication to the calculator that you'd expect in college-level math supplies. It'll make homework easier, your work more visible on a computer, and give your calculator a longer life span. Many consider the connectivity and rechargeable battery to be the best aspects of the TI-NSpire CXII's design. The battery should last for around three years. Rechargeable Battery: Fully charged, it will last for up to two weeks.Connectivity: You can connect the CX II to a computer.Memory: 90+ MB of dedicated storage memory and 64 MB of dedicated operating memory.Dimensions: Length 7.5" width 3.4" thickness 0.6".Weight: 12 ounces (that's not even a pound).If getting down to the nitty-gritty details, these specs can help you compare this calculator to other options. This calculator is relatively compact, so you won't have to worry about it hogging up space in your backpack. In general, you can use the CX II for the following exams: However, rules always change so it is a good idea to check with your local testing center first. Many states allow it for state standardized tests as well. Texas Instruments designed these models to be user-friendly, a gateway into the more complex graphing calculators used in intermediate and advanced college curriculum. With a little practice, anyone can use either CX II model, especially high schoolers and undergraduate students. ![]() The two different types of TI-NSpire-the CX II and the CX II CAS-are both great options for math students handling coursework or about to tackle national exams (SATs and ACTs). The TI-NSpire by Texas Instruments is arguably the most powerful and reliable calculator you can buy.
