Getting Started with TI-Nspire™ CX II Handhelds
The TI-Nspire™ CX II and the TI-Nspire™ CX II CAS are the newest handhelds in the TI-
Nspire™ family of products. Featuring a backlit colour display and a slimmer form, the
handhelds provide touchpad navigation, dynamic graphing and interactive computer
features.
The handhelds 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, taking 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.
