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.

Tracing a Plot

Graph Trace moves through the points of a graphed function, parametric, polar,

sequence or scatter plot. To enable the trace tool:

1. Press b > Trace > Graph Trace (b 5 1) to move across the plot

in Trace mode.

2. (Optional) To change the trace step increment for tracing, press

b 5 3.

After you type a different step increment, the Graph Trace tool moves

across the graph in steps of that size.

Use Graph Trace to explore a plot in the following ways:

• Move to a point and hover to move the trace cursor to that point.

Using the Scratchpad 35

36 Using the Scratchpad

• Press ¡or¢ to move from point to point on the function’s graph. The

coordinates of each point traced are displayed.

• Press £or¤ to move from one plot to another. The point’s

coordinates update to reflect the new location of the trace. The trace

cursor is positioned on the point of the new graph or plot with the

closest

value to the last point identified on the previously traced

function or graph.

• Type a number and press · to move the trace cursor to the point

on the plot with independent coordinates nearest the typed value.

• Create a persistent point that remains on the graph by pressing ·

when the trace point reaches the point you want to label. The point

remains after you exit Graph Trace mode.

Notes:

• The string

undef

is displayed instead of a value when you move over

a point that is not defined for the function (a discontinuity).

• When you trace beyond the initially visible graph, the screen pans to

show the area being traced.

3. Press d or choose another tool to exit Graph Trace.

Finding Points of Interest

You can use the tools on the Analyse Graph menu to find a point of interest in a

specified range of any graphed function. Choose a tool to find zero, the

minimum or maximum, the point of intersection or inflection or the numeric

derivative (dy/dx) or Integral on the graph.

1. Select the point of interest that you want to find on the Analyse Graph

menu. For example, to find a zero, press b 6 1.

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 non-

CAS 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.

Updating the Handheld Operating System

To take advantage of the latest handheld features and updates, download the

latest operating system files from the Education Technology website

(education.ti.com). You can update the operating system (OS) on TI-Nspire™

handhelds using a computer and the following software:

• TI-Nspire™ Teacher Software

• TI-Nspire™ Student Software

• TI-Nspire™ CAS Teacher Software

• TI-Nspire™ CAS Student Software

• TI-Nspire™ Navigator™ Teacher Software

• TI-Nspire™ CASNavigator™ Teacher Software

In the classroom, you can use the TI-Nspire™ Docking Stations to upgrade the

OS on multiple handhelds at the same time.

You can also transfer the OS from one TI-Nspire™ handheld to another or from

one TI-Nspire™ CX handheld to another. However, handheld operating

systems are not interchangeable. You cannot transfer a CAS operating system

to a non-CAS handheld and you cannot transfer a TI-Nspire™ handheld

operating system to a TI-Nspire™ CX handheld.

What You Need to Know

• If there is not enough room on the receiving handheld for the upgrade, a

message is displayed. For more information, See

Memory and File

Management.

• OS upgrade operations do not delete user documents. The only time

documents are affected by an OS installation is if the receiving handheld

has a corrupted OS. In this situation, documents may be affected by OS

restoration. It is a good practice to back up important documents and

folders before installing an updated operating system.

Warning: Upgrading the operating system will delete all TI-84 applications and

files. Before installing an OS upgrade, you should use TIConnect to back up all

TI-84 applications and files to a computer. You can copy them back to the

handheld when the OS upgrade is complete.

the receiving and sending handhelds:

• “

Receiving OS. Do not unplug cable.

”

• “

Sending OS. Do not unplug cable.

“

7. After the transfer completes, the sending handheld receives a completion

message and you can unhook the cable. The OS is automatically installed

on the receiving handheld. During the installation process, the “Installing

OS <

version number
