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, then finish the work at home to take advantage of the software’s full-color 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 recognize, 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.

Tracing a graphed function

Graph Trace moves through the points of a graphed function, parametric, polar, sequence, or scatter plot. To enable the trace tool:

1. Press

b51 to move across the points in a graphed function

in Trace model.

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

b53.

After you type a different step increment, the Graph Trace tool moves across the graph in steps of that size, instead of moving at the default step automatically defined with a function.

3. Use Graph Trace to explore a graphed function in the following ways:

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

Using the Scratchpad 21

• Press 7 or 8 to move from point to point on the function’s graph.

The coordinates of each point traced displays.

• Press 9 or : to move from one function’s graph to another, or to a scatter plot. 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 x value to the last point identified on the previously traced function or graph.

• Type a number and press · to move the trace cursor to that value on the function’s graph.

• Create a persistent point that remains on the graph while in Graph

Trace mode by pressing · when the trace point reaches

the point you want to label.

• Trace through and identify the points at which the function has no defined x or y value (a discontinuity). The string undef displays instead of a value when you move over a point that is not defined for the function.

Notes:

• When you select or trace a function on the work area, that function displays on the Edit Line.

• When you trace beyond the initially visible graph, the screen pans to show the area being traced.

4. Exit Graph Trace by pressing d or by choosing another tool.

Finding points of interest

You can use the tools on the Analyze 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

Graph

menu. For example, to find a zero, press b61.

The icon for the selected tool displays at the top left on the work area. Point to the icon to view a tooltip about how to use the selected tool.

2. Click the graph you want to search for the point of interest, then click a second time to indicate where to start the search for the point.

22 Using the Scratchpad

Analyze

The second click marks the lower bound of the search region and a dotted line displays.

Note: If you are finding the derivative (dy/dx), click the graph at the point (numeric value) to use for finding the derivative.

3. Press 3 or 4 to move the dotted line that marks the search region, then click the point at which you want to stop the search (upper bound of the search region).

4. Press

· at the point to start the search. The tool shades the range.

If the search region you specified includes the point of interest, a label for the point displays. If you change a graph that has points of interest identified, be sure to check for changes in points of interest. For example, if you edit the function on the entry line or manipulate a plot, the point where the graph intersects zero can change.

The labeled points of interest remain visible on the graph. You can exit the tool by pressing

d or choosing another tool.

Working with variables in the Scratchpad

Scratchpad variables are shared between Scratchpad Calculate and Scratchpad Graph, but not with any TI-Nspire™ documents. If you use the same name for a Scratchpad variable and a variable in a document, no conflict occurs unless you attempt to copy expressions between documents and the Scratchpad.

Transferring files to and from handhelds

You can send documents, Operating System (OS) files, and folders to another TI-Nspire™ handheld.

72 Connecting handhelds and transferring files

Rules for transferring files and folders

• You can transfer documents and Operating System (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 TI-Nspire™ 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 TI-Nspire™ 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, then the name of the transmitted file will be truncated to enable the software to follow the renaming scheme described in the previous bullet.

• All variables associated with the document being transmitted are transferred with the document.

• Transmissions will time out after 30 seconds.

Caution: Some older TI-Nspire™ handhelds cannot receive folders; only

files. If you receive an error in sending to an older TI-Nspire™ handheld, see Common error and notification messages.

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 web site (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™ 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. See Memory and file management for more information about restoring memory.

• 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.

TI-Nspire™ CX handheld and you cannot transfer the OS on a CAS handheld to a non-CAS handheld. The operating systems are not the same and are not interchangeable.

To transfer the OS from one handheld to another:

1. Ensure any open documents on the receiving handheld are closed.

Updating the handheld operating system 89

2. Connect the two handhelds using a USB mini-B to mini-B USB cable.

3. On the sending handheld, select My Documents from the Home screen.

4. Press b, then select Send OS. On a TI-Nspire™ handheld, press b.

5. On the receiving handheld, the message, “You are receiving an OS Upgrade. Unsaved changes will be lost. Would you like to continue?“ is displayed along with Yes and No response buttons. Select Yes to

receive the OS upgrade.

•If Yes is not selected within 30 seconds, the handheld

automatically responds with No, and the transmission is cancelled.

• It is important to save and close all open documents before

performing an OS Upgrade. Continuing with an OS Upgrade on a handheld with an open, unsaved document will cause the loss of that data.

6. While the upgrade is in progress, the following messages are displayed on 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>” message is displayed on the receiving handheld.

8. When the installation is complete, the “OS <version number> has been installed. Handheld will now restart.” message is displayed. The restart is initiated. If the sending handheld is still attached to the cable, the successful transmission message remains displayed on that handheld’s screen.

Important:

• For each receiving handheld, remember to back up information as necessary and install new batteries.

• Be sure the sending handheld is on the Send OS screen.

Upgrading the OS on multiple handhelds

In the classroom, use the TI-Nspire™ Docking Station to upgrade the OS on multiple handhelds at the same time.

In the teacher versions of the TI-Nspire™ software, you can transfer files from the computer to multiple handhelds from the Content Workspace. See Using the Content Workspace for more information about transferring files to connected handhelds.
