TI-Nspire CAS features all the functionality of TI-Nspire family technology, plus built-in CAS (Computer Algebra System) capabilities.
New features for the classroom:
Built-in interactive geometry capabilities.
Interactive "Grab-and-Move"– make changes to a graph and graphed functions – in real time – to observe relationships and the impact of changes to corresponding equations and data lists.
Multiple Representations - See multiple representations of a single problem - algebraic, graphical, geometric, numeric and written. Explore individual representations, one at a time, or as many as four on the same screen.
Research shows that students learn mathematical concepts more readily with deeper understanding when they learn across different forms of representation.
TI-Nspire CAS Applications – the ability to see and explore multiple representations is supported by the following built-in applications:
CALCULATOR - Enter and view expressions, equations and formulas exactly as they appear in math textbooks. Quickly and easily select the proper syntax, symbols and variables from a template that supports standard mathematical notation. Scroll through previous entries to explore outcomes and patterns.
GRAPHS & GEOMETRY - Graph equations, expressions and other functions. Then make changes to variables to see how the values in dynamically linked tables and equations will also change, in real time. Integrate graphing and geometry on the same screen to help reveal connections between concepts in algebra and geometry. Includes polar graphing functionality.
LISTS & SPREADSHEET - Capture and track the values of a graph and collected data, and observe number patterns. Organize the results of statistical analysis. Capabilities similar to using computer spreadsheets: label columns, insert formulas into cells, select individual cells and change their size, and more.
DATA & STATISTICS - Summarize statistical data using different graphical methods. Manipulate and explore data - watch how changes in data can affect the statistical analysis. Create "quick graphs". Perform a variety of de*ive and inferential statistical calculations on real data sets
NOTES - Put the math in writing. Include the word problem with its solutions and explain problem-solving approaches - right in the handheld or computer software. Question-and-answer templates allow educators to prompt students to show solutions.
Dynamic linking - means that changes made to one representation of a problem are automatically reflected in others of that same problem, all in real time.
Programming - features a dedicated programming environment as well as programming libraries for global access to user-defined functions & programs
Easy-to-use computer features:
Simple drop-down menus - emulate the intuitive operation of familiar computer features
NavPad computer-like cursor contro
