|Do not use for hard core statistics, engineering, or science. Kay, I know my review is going to be seen as a bit harsh, and to be fair it IS but... broke within a year I bought this for my son and it just stopped working about 12 1/2 weeks after purchase. Now he needs a new one for AP CALC.|

|Difficult, cumbersome, frustrating I give this calculator two stars because it has a lot of functionality. Broken promise of delivery I paid for one day shipping, and now they tell me it will take two days after placing the order for delivery.|

Updating your handheld operating system
You can update the OS on your TI-Nspire handheld using your computer and TI-Nspire Computer Link or Connect-to-Class software. You can also transfer the OS from one handheld to another. OS upgrade operations do not delete user documents. If there is not enough room on the receiving handheld for the upgrade, the sending handheld is notified. The only time documents can be 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 backc up your important documents and folders before installing an updated operating system. Refer to the important information here and in the TI-Nspire Computer Link or Connect-to-Class software documentation before performing an OS update.
Important operating system download information
You should always install new batteries before beginning an OS download. When in OS download mode, the APD feature does not function. If you leave your handheld in download mode for an extended time before you begin the downloading process, your batteries may become depleted. You will then need to install new batteries before downloading.
Finding operating system upgrades
Your TI-Nspire Computer Link or Connect-to-Class software has convenient links to a number of useful Texas Instruments web sites, including handheld OS updates. You will need an Internet connection and the appropriate USB cable to download the updates.
Backing up files to a computer
Use the TI-Nspire Computer Link software to back up the contents of your handheld to a computer. When using the TI-84 Plus keypad, use TIConnect to back up. TI-Nspire Computer Link software and TI Connect software are available on the product CD that came with your handheld.
Working with documents
All of the work you do with the TI-Nspire handheld is contained in one or more documents, which you can share with other handheld users, and those using the desktop software. Each document is divided into at least one, and up to 30, problems. Each problem contains at least one, and up to 50, pages. Each page can be divided into as many as four work areas. Each work area can contain any of the TI-Nspire math and science learning technology applications (Calculator, Graphs & Geometry, Lists & Spreadsheet, Data & Statistics and Notes).
Creating a new document
Press c 6 to open a document from the home menu, or use the shortcut keys. Shortcut keys: / N A new document opens and displays a blank page with the Add Application menu.

Using multiple applications on a page
You can use up to four applications on each page. When you create a new document, it contains space to add one application. If you need to add more than one application to a page, you can change the layout to accommodate as many as four applications. You can choose a standard layout, provided as a menu item, or you can customize a layout to suit your needs.
Note: Press / c to Undo a file or folder deletion.
Duplicating documents and folders
Use Copy / C and Paste / V to duplicate documents and folders. To copy a document to another folder, select the desired folder, then paste.
Recovering deleted documents
Most operations performed in My Documents can be undone. Press / Z (Undo) to cancel the last operation until the deleted document is restored.
Sending a document to another handheld
You can send documents and Operating System (OS) files to another TI-Nspire handheld.
Rules for sending files
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 a document called Mydata existed on the receiving TI-Nspire handheld, it would be renamed Mydata(2). Both the sending and receiving units 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 unit and the file names contain 255 characters, then the name of the transmitted file will be truncated to allow the software to follow the renaming scheme described in the previous bullet. All variables associated with the document being transmitted are transfered with the document. Transmissions will time out after 30 seconds.
1. Open My Documents. Press c 7. 2. 3. Press the 5 and 6 keys on the NavPad to highlight the document you want to send. Select Send from the My Documents menu. Press / c 1 5.

For example, the context menu for a triangle also contains the Hide/Show, Delete, Length, and Area options. The following examples show the context menu for a function and a circle.
Context menu for a function (analytic object)
Context menu for a geometric object
The work area
The work area graphs the expressions that you type on the entry line. When you select or position the mouse over a function graph, the corresponding expression displays. Multiple expressions display when you select multiple plots. Plots that you can manipulate display tooltip instructions on how to change the vertical or horizontal orientation of the graph. When you select or position the mouse over a function graph, the corresponding expression displays. Multiple expressions display when you select multiple plots. Plots that you can manipulate display tooltip instructions on how to constrain manipulation to either the horizontal or the vertical dimension. There are two work area views available: Graphing View Plane Geometry View
The Graphing view
The Graphing view is the default Graphs & Geometry work area display. It contains: the default Cartesian axes in the Zoom Standard format (1:1 scale). the entry line from which you can graph up to 100 functions.
The axes, entry line, and grid can all be displayed or hidden in Graphing view. All objects created in Graphing view are analytic objects, so no scale displays for shapes you draw (such as a circle or triangle). The Show Scale tool has no effect.
The Plane Geometry view
The plane geometry view removes the axes and entry line from the work area to enable you to draw geometric shapes and explore them. In Plane Geometry view, you can display and set a scale for your drawings. To change to Plane Geometry view: 1. From the View menu, select Plane Geometry View. Press b 2 2. 2. The display refreshes to clear the axes and entry line and display a default scale. Any graphs or drawings created in graphing view are not displayed on the plane geometry area.
To return to Graphing view: From the View Menu, select Graphing View. Press b 2 1. The display refreshes to show the axes and entry line. Note: Any geometric constructions created while in the plane geometry view are retained and displayed along with any previously created graphs.
The analytic window
The analytic (graphing) window is available in the Plane Geometry view. It adds an analytic (graphing) window on top of a portion of the plane geometry work area. This provides a combination work area that enables you to use both work area types without toggling the view between them.
To open the analytic window: 1. 2. Ensure that the work area is in Plane Geometry view. From the View menu, select Show Analytic Window Press b 2 3. 3. A reduced size graphing window opens on the lower left corner of the plane geometry space.
Plane Geometry area
Modeling view - shows the previous two views and the work done on both.
You can alter the work area, without changing the view, to temporarily: Hide the axes. Any graphs or objects remain displayed on the work area. Show or hide axis end values and show or hide a grid in the graphing window. Hide or show the entry line by clicking Hide the axis scale values. Resize the axes using the zoom tools or by dragging tic marks.
To display more of the plane geometry work area, pan the screen.
To remove the analytic window from the work area
From the View menu, select Hide Analytic Window Press b 2 3.
Object behavior in different views
When you create an object in the graph area, it is called an analytic object, and all points of the object reside on the graph plane. When you change the axes scale, you automatically affect the appearance of the object. If you calculate a value associated with the object such as the area, only generic units are assigned (u for unit). These objects remain associated with the coordinate plane until you delete them or redefine them to the plane geometry area. When working with a modeling view work area, you cannot move an analytic object onto the plane geometry area. When you create an object in the plane geometry area, it is a geometric object. These objects can have an assigned scale, such as miles or centimeters, instead of u for units. You can lock a point, such as one vertex of a triangle, on the work area, but since the object is not tied to a coordinate plane, you cannot display coordinates for that vertex. When working with a modeling mode work area (Plane Geometry view with analytic window), you can move a geometric object into the graphing work area. The object remains a geometric object, and is not associated with the axes. The examples below show a modeling work area and the two types of objects: A is an analytic object while B is a geometric object.
While the two circles appear identical, they do not behave in the same way. Analytic objects are impacted when the graph area is altered. In the next example, the axes were altered. Notice that only Circle As appearance is affected by the change.
If you construct an object while the axis is hidden, the object created will be a geometric object. However, if you construct an analytic object and later hide the axis, the object remains an analytical one.
Triangle as it appears in Graphing view. The unlabeled vertex remains a geometric point.
Summary of differences
Feature Aspect Ratio Units of Measure Area Graph Type Uses Graph Area Adjustable; initially 1:1 Generic (displayed as u) Cartesian (default) or Polar Define and graph functions to: Graph functions of the form f (x) Create scatter plots Graph polar equations Graph parametric functions Graph sequences Plane Geometry Area Always 1:1 (static) User-defined (per scale) Euclidian Construct Euclidean objects Create transformations Determine measurements (for example, length, angle, or area)
Construct analytic objects Label equations Identify coordinates for discrete points Geometric constructions can be moved into the analytic area but remain geometric in nature.
Analytic constructions must remain in the analytic area.
Creating and manipulating axes
When you add the Graphs & Geometry application to a page, Cartesian axes displays by default. You can change the appearance of your axes in the following ways: 1. Adjust the length of the axes: When using Plane Geometry view with Show Analytic Window,
Select an axis and retype the domain or range labels. Click any tick mark on the axis scale and drag to increase or decrease the numbers on the scale and tick mark spacing.
The aspect ratio of the axes is retained. To modify the scale of only one axis, press g as you adjust the value or drag the line.
Default range and domain
Use the Zoom tool options to adjust the view. Adjust the end style of the axes using the Attributes tool. Display the Attributes tool by: Using the NavPad arrows to move to the axes and pressing
pressing / and clicking an axis between two tick marks. Press the left and right arrow keys to display the desired end style. The context menu also enables you to select a Zoom tool. 4. Adjust the axes scale and tic mark spacing manually. a) Click and hold one tic mark, and move it on the axis. The spacing and number of tic marks increases (or decreases) on both axes.
To adjust the scale and tic mark spacing on a single axis, press and hold g, and then grab and drag a tic mark on that axis.
Change axis end values by double-clicking them and typing new values. Adjust the location of the axes.
