Function and Applications

The TI-Nspire™ CX numeric handheld device and companion software are designed for teaching, learning and exploring mathematics and its applications. In addition to the flexibility offered by the TI-Nspire™ numeric handheld device's simple, menu-driven document structure, the TI-Nspire™ CX handheld numeric device is enhanced by a backlit colour screen with the ability to import images and overlay graphs and other elements, bringing concepts to life. A powerful teaching and learning tool as well as an exam calculator where graphics are permitted. In addition can be used to program the TI-Innovator™ System.


  • "2 in 1": Packaging includes handheld and companion software (for PC/Mac®)
  • Slim handheld with full-colour backlit display, touchpad and 100 MB RAM; includes rechargeable battery
  • Software allows for larger visualisation, more detailed work with data, programming and authoring on the computer
  • The user may create and modify documents on either the handheld device or computer software application, and also seamlessly exchange files between handheld and computer as well as connect to projectors and interactive whiteboards
  • Ability to import digital images onto the handheld screen as well as in the computer software
  • Five dynamically linked applications: Calculator, Graphs & Geometry, Lists & Spreadsheet, Data & Statistics, Notes
  • 3-D Graphing View plots surfaces which can be defined as z = f (x, y)
  • Supports data logging for collection and analysis of real-life data and science experiments using the Vernier DataQuest™ application for TI-Nspire™ technology

  • Interactive analysis of function values, roots, maximums, minimums, integrals and derivatives
  • Six different graph styles and 15 colors to select from for differentiating the look of each graph drawn
  • Matrix operations: transpose and augment matrices; use elementary row operations; find inverse, determinant and reduced row echelon forms; convert matrices to lists and vice versa; calculate eigenvalues and eigenvectors
  • List-based one- and two-variable statistical analysis, including logistic, sinusoidal, median-median, linear, logarithmic, exponential, power, quadratic polynomial, cubic polynomial, and quartic polynomial regression models
  • Three statistical plot definitions for scatter plots, xy-line plots, histograms, regular and modified box-and-whisker plots, and normal probability plots
  • Advanced statistics analysis, including 10 hypothesis testing functions, seven confidence interval functions and one-way analysis of variance
  • Eighteen probability distributions functions, including the cumulative distribution function (CDF), probability density function (PDF) and inverse probability distribution function for normal, chi-squared, t-, and F- distributions; and the CDF and PDF for binomial, geometric and Poisson distributions
  • Built-in interactive geometry capabilities
  • Quick alpha keys
  • Simple drop-down menus - emulate the intuitive operation of familiar computer features
