Texas Instruments TI-NSPIRE-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.

In the context of the Texas Instruments TI-Nspire CAS calculator, CAS stands for Computer Algebra System.

The main difference between TI-Nspire and TI-Nspire CAS is the presence of a Computer Algebra System (CAS) in the latter.
TI-Nspire is a graphing calculator that allows users to perform various mathematical operations, create graphs, and solve equations. It is mainly used for standard mathematical calculations and representations.
TI-Nspire CAS, on the other hand, includes a CAS feature which provides advanced algebraic capabilities. It can perform symbolic calculations, solve equations symbolically, simplify expressions, and even perform calculus operations symbolically. This makes it more suitable for advanced mathematics, such as calculus, algebra, and other subjects that involve complex equations and expressions.
In summary, TI-Nspire is a graphing calculator with basic mathematical capabilities, while TI-Nspire CAS includes a Computer Algebra System for advanced mathematical calculations.

TI-Nspire CAS stands for Texas Instruments-Nspire Computer Algebra System.
