TI-Nspire™ CAS6.4.0 - App Store

Texas Instruments, the No. 1 recommended brand of graphing calculators in the U.S., has optimized its most powerful Computer Algebra System (CAS) math engine for an all-in-one iPad app that makes teaching and learning math more engaging, meaningful and ... fun!

ONE CAS APP. ALL THE MATH.

Open the door to math mastery with the first-in-class iPad CAS app that delivers comprehensive graphing, data entry and analysis, statistical modeling and calculating functionality.

Solve equations with algebraic precision, factor and expand variable expressions, complete the square, find antiderivatives, compute limits, find exact solutions in irrational form and more.

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

Visualize crucial connections by observing how equations change - in real time, on one screen - when you touch, grab and interact with shapes, graphs and objects on the screen.

Graph functions, inequalities, implicit functions, conic sections, scatter plots, statistical plots and regression models, 3D graphs, parametric, polar and differential equations.

Enter equations in proper math notation so math symbols and formulas on the screen are identical to those in text books and on the board.

Deepen understanding by exploring hundreds of free activities for Pre-Algebra, Algebra, Geometry, Calculus, Statistics, Pre-Calculus and more from the online Math Nspired resource center.

Create and store work on your iPad, and share it using your Email or Dropbox account.
