TI-Nspire™ CAS App for iPad®

Texas Instruments, the No. 1 recommended provider of educational graphing calculators in the U.S., now offers the most powerful all-in-one Computer Algebra System (CAS) app that meets critical math curriculum needs for students ages 14 to 21.


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.

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

CAS Functionality

Calculate precise values with powerful CAS functionality that enables you to perform both symbolic and standard numeric calculations.

Perform calculations in proper math notation.
Lists & Spreadsheet
Combine spreadsheet functionality with mathematical operations.
Plot, explore and animate functions, equations and inequalities.
Data & Statistics
Dynamic graphing and interactive analysis of data.
Construct and explore dynamically geometric figures and properties.
Create interactive activities, documents or reports.

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.*
