Getting Started with the TI-Nspire™ Handheld

The TI-Nspire™ handheld and the TI-Nspire™ CAS handheld are the second generation handhelds in the TI-Nspire™ family of products. These handhelds provide touchpad navigation, dynamic graphing, and interactive computer features.

The handheld and the TI-Nspire™ software share the same functionality, enabling you to transfer class assignments from the handheld to the computer or transfer documents to the handheld when you need to be mobile. Start assignments at school, and then finish the work at home to take advantage of the software’s full-color display and easy-to-use navigation. Use the software to download the latest software and handheld operating system updates as they become available to ensure you have the latest enhancements.

This guide covers both the TI-Nspire™ handheld and the TI-Nspire™ CAS handheld. While they operate identically in many ways, there are a few distinctions. If the TI-Nspire™ CAS handheld has additional functionality, it is pointed out and the CAS operation is described.

About CAS

With CAS, or the Computer Algebra System, you can:

• Perform both symbolic and numeric calculations.

• Factor and expand expressions and solve for common denominators.

TI-Nspire™ CAS technology makes it possible to recognize, simplify, and calculate math expressions, preserving the symbols including variables and terms such as “e” and p.

This ability to enter and view equations and expressions on screen as they appear in textbooks is especially useful for step-by-step, arithmetic, algebraic, and calculus calculations.

Transferring Files to and from Handhelds

You can send documents, Operating System (OS) files, and folders to another TI-Nspire™ handheld.

Rules for Transferring Files and Folders

• You can transfer documents and OS files.

• Operating systems are not interchangeable between different handheld types. For example, you cannot transfer a CAS operating system to a nonCAS handheld.

• If a document with the same name as the one you are sending already exists on the receiving handheld, the document will be renamed. The system appends a number to the name to make it unique. For example, if Mydata existed on the receiving handheld, it would be renamed Mydata (2).

Both the sending and receiving handhelds will display a message that shows the new name.

• There is a 255-character maximum length for a file name, including the entire path. If a transmitted file has the same name as an existing file on the receiving handheld and the file names contain 255 characters, the name of the transmitted file will be truncated to enable the software to follow the renaming scheme described in the previous paragraph.

• All variables associated with the document being transmitted are transferred with the document.

• Transmissions will time out after 30 seconds.

Caution : Some older TI-Nspire™ handhelds cannot receive folders; only files. If

you receive an error in sending to an older TI-Nspire™ handheld, see
