• CAS functions (only applies to TI-Nspire™ CX II-T CAS)
• Deactivate CAS (only applies to TI-Nspire™ CX II-T CAS)
• Multiple graphical display functions that can be simultaneously defined, stored, displayed and analyzed
• User-defined list names in lists & spreadsheets
• Eleven interactive zoom functions
• Numerical evaluations in table format for all diagram modes
• Interactive analysis of function values, roots, maximum values, minimum values, integrals and derivatives
• Six different chart types and 15 colors are available to change the appearance of each chart
• The matrix operations include reciprocal, determinant, transpose, extension, staircase normal form and elementary series. Convert matrices to lists and vice versa.
• List-based statistical analysis with one and two variables, including logistic, sinusoidal, median-median, linear, logarithmic, exponential, power, quadratic polynomial, cubic polynomial and biquadratic polynomial regression models
• Three statistical plot definitions for point clouds, xy line plots, histograms, regular and modified box and whisker plots and normal probability plots
• Advanced statistical analysis, including 10 hypothesis test functions, seven probability of certainty functions and one-way variance analysis
• Eighteen distribution functions for probability theory, including cumulative distribution function (KVF), probability density function (WDF), and inverse probability distribution function for normal, chi-square, t, and F distributions, plus KVF and WDF for binomial, geometric, and Poisson distributions
• Integrated interactive geometry functions
• Fast operation with alpha keys
• Simple drop-down menus recreate the intuitive operation of familiar computer functions
• TI-Nspire™ documents (.tns files)
• Use of images (file formats JPEG, JPG, BMP, PNG) that can be overlaid with graphic elements
• Students examine mathematical expressions in symbolic form, see patterns and understand the mathematical processes underlying the formulas.
• Multiple representations of a single problem: algebraic, graphical, geometric, numerical and written.
• Chem Box allows convenient entry of chemical formulas and equations
• Editing a representation immediately updates the linked representations and thus displays meaningful connections without changing screens. For example, you can move a function displayed as a graph to see how it affects corresponding equations and data lists.
• A special programming environment including programming libraries allows comprehensive access to user-defined functions and programs.
• Updates possible of operating system (OS) and software Support of measured value acquisition
• Compatible with TI-Nspire Lab Cradle, Vernier EasyLink USB sensor and Vernier EasyTemp temperature sensor to collect and analyze real data
