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-colour 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 recognise, 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.

TI-Nspire™ Handheld Keys

Use the TI-Nspire™ Touchpad as you would a laptop touchpad.

You can also press the outer edges to move right, left, up, and

down.
