[. . . ] This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ?Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

Using Geometry Trace The Geometry Trace tool enables you to leave a visible trail of an object when it is moved on the work area. Click the object or function and manually grab and move the object, or select a point and use the Attributes tool to set animation. If you use animation, the point must be selected for Geometry Trace as well as animation. In the following example, a line segment was drawn and selected for Geometry Trace. Movement of the segment was done manually. The amount of trace track displayed on the work area depends upon the amount of movement. If the object moves very little, then the entire track remains displayed until you erase it. If the object moves a lot, the track can obscure a significant portion of the work area. In this case, the older portions of the Graphs & Geometry 305 track fade out to prevent the work area from becoming obscured by the track. Erasing Geometry Trace The easiest way to remove the trace tracks from the work area is to select the Erase Geometry Trace tool. When selected, this tool removes immediately all trace tracks from the work area. Grouping objects You can group objects on the work area to maintain the positioning of the objects and to perform certain actions on all of the objects in the group. For details about selecting the objects to group, see Selecting objects with the Pointer tool or Selecting objects with the Select tool. Move to the place where you want to anchor the point coordinaties and press . If you move the point to a different location, the new coordinates are updated to the new position. 310 Graphs & Geometry Naming a point You can name points and vertices in either the Graphing or Plane Geometry view. Because they are not tied to a specific coordinate, names remain unchanged if you alter the location of any portion of an object. (Optional) You can name a point as you create it by typing a letter or name immediately after you define the point. and ?z?for the remaining two vertices as you create them. Redefining a point You can redefine a point from a point on the work area to an object, from one object to another, or from the analytic window to the Plane Geometry View work area (or from the geometric work area to the analytic window). Create a point, or decide which existing point you want to redefine. 2. Click the point you want to redefine, then click the object or work area at the location for the redefinition. The point moves to the object or new location. Graphs & Geometry 311 Working with linear objects The linear objects you can create and explore are located on the Points & Lines menu. Note: If you press and hold g while creating the line, you limit its orientation (relative to the x-axis or the horizontal aspect of the screen), by 15- increments. Move and click again to define the direction and second point of the line. Note: If you press and hold g while while creating the ray, you limit its orientation, relative to the x-axis or the horizontal aspect of the screen, by 15- increments. Graphs & Geometry draws the ray. 312 Graphs & Geometry Lengthening the visible part of a line or ray 1. [. . . ] In the teacher software, click to open the drop-down menu and select a view.

Working with documents You can open multiple documents in the workspace by selecting File > Open Document from the menu or using keyboard shortcuts. When you switch between these documents, the emulated handheld shows only the current document. menus or shortcuts. Opening a document You can open a document by navigating to it on the emulator, the same way you open a document on the handheld, or you click File > Open Document. Using the TI-SmartView? [. . . ]
