TI-Nspire™ CAS App for iPad®

Texas Instruments, the No. 1 recommended brand in graphing calculators, now offers its most powerful graphing technology in an all-in-one Computer Algebra System (CAS) app for iPad® that makes teaching and learning math more engaging, meaningful and … fun!

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

Perform computations and enter expressions, equations and formulas in proper math notation.
gen-product-app-icon-spreadsheets Lists & Spreadsheet
Perform mathematical operations on data and visualize the connections between the data and their plots.
Plot and explore functions, equations and inequalities, animate points on objects and graphs, use sliders to explain their behavior and more.
Data & Statistics
Summarize and analyze data using different graphical methods such as histograms, box plots, bar and pie charts and more.
Construct and explore geometric figures and create animations.
gen-product-app-icon-notes Notes
Enter notes, steps, instructions and other comments on the screen alongside the math.

Open new paths to understanding

New and faster interactive features motivate students to see and interact with math and science more deeply:

Animated path plot
Visualize function, parametric and polar graphs as they are drawn in real time.

Dynamic coefficient values
Explore direct connections between dynamic coefficients in equations and graphs.

Points by coordinates
Create dynamic points defined by coordinates, sliders or expressions quickly.

Tick-mark labels
Label axes scales to create visual contexts that promote understanding.

In addition to those new features, TI-Nspire™ CAS App for iPad® enhancements also include:

deSolve wizard

Reduce syntax errors in solving differential equations.


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.*

All your work, on the go, on your iPad®

The app fits seamlessly into existing TI-Nspire™ environments so class activities and homework can be created on the iPad®,
TI-Nspire™ graphing calculators and teacher and student software, then used on any — or all — of the platforms.

CREATE class activities and homework, complete with dynamically linked notes, directions, and instructions.

SHARE work across platforms using email, iTunes® file sharing and Dropbox™ for unlimited portability.

SAVE work as simply as saving documents on a computer.
