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.
This guide covers the following TI-Nspire™ CX II handhelds:
• TI-Nspire™ CX II / TI-Nspire™ CX II CAS
• TI-Nspire™ CX II-T / TI-Nspire™ CX II-T CAS
• TI-Nspire™ CX II-C CAS
• TI-Nspire™ CX II EZ-Spot
While they operate identically in many ways, there are a few distinctions. If there are
differences between the Numeric, Exact Arithmetic, or CAS handhelds, it is pointed out
and the appropriate operation is described.
About Maths Modes
TI-Nspire CX II handhelds perform calculations in one of three modes: Numeric, Exact
Arithmetic, or Computer Algebra System (CAS).
Numeric mode supports results in terms of floating point numbers, integers, and
stacked fractions only.
Exact Arithmetic mode supports results in terms of floating point numbers, integers,
stacked fractions, p, e, radicals ‡, and other constants such as ln(5) and sin(2).
CAS mode supports the same results as Exact Arithmetic as well as symbol
manipulation such as x+x, and CAS functions such as symbolic factoring, solving
equations, limits, and indefinite integration.
The maths modes that are available will depend on which TI-Nspire CX II handheld
model you have:
