TI-Nspire CAS App for iPad
Built from the platform that powers the innovative TI-Nspire™ Technology, the TI-Nspire CAS App for iPad delivers all-in-one functionality that provides reliable, comprehensive computational and analytic tools and capabilities.

CAS Functionality
Symbolically solve equations, factor and expand variable expressions, complete the square, find antiderivatives compute limits, find exact solutions in irrational form and more.
gen-product-app-icon-calculator CALCULATOR
Perform computations and enter expressions, equations and formulas in proper math notation using a unique interactive keyboard.
gen-product-app-icon-data-lists DATA AND STATISTICS
Summarize and analyze data using different graphical methods such as histograms, box plots, bar and pie charts and more.
gen-product-app-icon-graph GRAPHS
Plot and explore functions, equations and inequalities, animate points on objects and graphs, use sliders to explain their behavior and more.
gen-product-app-icon-spreadsheets LISTS AND SPREADSHEETS
Perform mathematical operations on data and visualize the connections between the data and their plots.
gen-product-app-icon-geometry GEOMETRY
Construct and explore geometric figures and create animations.
gen-product-app-icon-notes NOTES
One touch toggles the interactive keyboard from math notation to an alphabetic configuration so notes, directions and steps can be entered alongside the math.

Accelerate the Understanding Process

By supporting a hands-on, powerfully visual approach to learning, the TI-Nspire CAS App for iPad changes the way students experience math and helps them master deep conceptual understanding.
gen-product-icon-multiple-reps Multiple representations enable students to visualize the connections between algebraic, graphical, geometric, numeric and written forms of problems.
gen-product-icon-dynamiclinking Dynamic linking across the multiple representations encourages students to make crucial connections by observing how equations change — in real time, on one screen — as they touch, grab and interact with shapes, graphs and objects on the screen.

Enter Expressions in Proper Math Notation

The unique interactive keyboard features equation templates so students can enter values and see proper math notation just as it is printed in textbooks and on the board.

Make Real-World Connections

Make math more meaningful by importing images from the iPad camera or photo library and overlaying graphs and equations on them to illustrate math principles in the real world.*
