Texas Instruments NSPIRE-CX-CAS user manual

The main difference between Texas Instruments (TI) graphing calculators with computer algebra system (CAS) capability and those without CAS is the functionality that they offer.
1. CAS Functionality: TI calculators with CAS have a built-in computer algebra system, which allows for symbolic manipulation of algebraic expressions, equations, and calculus operations. These calculators can perform tasks like solving equations symbolically, simplifying algebraic expressions, and performing indefinite and definite integrations. This makes them more powerful for advanced mathematics and engineering applications.
2. Non-CAS Functionality: TI calculators without CAS have limited symbolic manipulation capabilities. They primarily function as graphing calculators and can perform numerical calculations, graph functions and equations, plot data points, and solve equations numerically but not symbolically. These calculators are typically used for basic and intermediate mathematics courses where symbolic manipulation is not required.
3. Use in Examinations: Many standardized exams, like the SAT, ACT, AP, IB, and some college exams, allow the use of non-CAS graphing calculators but prohibit the use of calculators with CAS functionality. This is to prevent students from relying on the CAS system to solve problems that are intended to be solved manually.
4. Cost: TI calculators with CAS capabilities are often more expensive than their non-CAS counterparts, as they offer more advanced features and functionality. The inclusion of the CAS system adds complexity and increases the manufacturing cost.
In summary, Texas Instruments calculators with CAS functionality provide the ability to perform symbolic manipulations and engage in advanced mathematical operations not available on non-CAS calculators. However, the use of CAS calculators may be restricted in exams, and they are generally pricier compared to non-CAS models.

The TI-Nspire CX CAS calculator is allowed on most standardized tests, including the SAT, ACT, and AP exams. However, it is always recommended to check with the specific test organizer or College Board to ensure the calculator is allowed for a particular exam.

The main difference between TI-Nspire CAS and CAS CX is the design and appearance of the calculator. The CX version, which stands for Color eXtension, features a full-color backlit display, making it more visually appealing and providing a better user experience.
In terms of functionality, both versions have the same capabilities as a Computer Algebra System (CAS) calculator, allowing users to perform complex mathematical calculations, solve equations, manipulate algebraic expressions, and more. They can also handle graphing, including plotting functions, parametric equations, and inequalities.
However, the CX version offers some additional features and improvements. It has a faster processor, enabling quicker calculations and graphing. It also has more built-in memory and storage capacity for saving files and programs. Additionally, the CX version supports wireless connectivity, allowing users to transfer data and files between calculators and computers.
In summary, the TI-Nspire CAS CX is an upgraded version of the TI-Nspire CAS, offering a more modern design, enhanced display, better processing power, increased memory, and wireless connectivity.
