a few distinctions. If the TI-Nspire™ CX 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.

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.
• 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. You can
trace multiple functions as described in Tracing all graphs.
• 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 Analyze
Graph menu. For example, to find a zero, press b 6 1.
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.
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).
SPG_POI.gif

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

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

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.

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.
