Understanding The Scratchpad; Libraries; Program Editor - Texas Instruments TI-nSpire CAS Getting Started

Handling errors resulting from sending folders
If you receive an error after attempting to send, it may mean the
receiving handheld has an operating system that does not support the
transfer. To resolve this, update the receiving handheld's OS and try the
send again.

Understanding the scratchpad

The scratchpad allows you to make quick calculations without affecting
your current document. You can open the scratchpad application, do
your calculation, and then discard it or save the contents of the
scratchpad to the current document or a new document.

Libraries

A library is a TI-Nspire™ document that contains a collection of variables,
functions, and/or programs that have been defined as library objects.
Unlike ordinary variables, functions, and programs, which can be used
only within a single problem (the problem in which they are defined),
library objects are accessible from any document. You can even create
public library objects that appear in the TI-Nspire™ Catalog.
For details, see the "Libraries" chapter of this documentation, available
on the CD that came with your handheld or on the Texas Instruments
web site, http://education.ti.com.

Program Editor

The Program Editor helps you define, edit, and manage user-defined
functions and programs.
• The editor has dialog boxes to help you define functions and
programs using correct syntax.
• The editor lets you enter multiple-line programming statements
without requiring a special key sequence to add each line.
• You can easily create private and public library objects (variables,
functions, and programs).
For details, see the Programming chapter of this documentation,
available on the CD that came with your handheld or on the Texas
Instruments web site, http://education.ti.com.
