[. . . ] 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. [. . . ] The dotted line changes to a solid line. 284 Graphs & Geometry Moving a vector 1. Click on any point other than the endpoint and drag the vector to the desired location. Resizing a vector Select an end point and drag it to increase or decrease the magnitude of the vector. Note: If the endpoint is located on an axis or another object, you can only move the endpoint of the vector along that object. Creating a tangent You can create a tangent by identifying a specific point on an existing object or function. On the work area, select the point at which you want the tangent drawn. Press to anchor the tangent on the work area. Tangent of an object Creating and working with shapes You can use the Shape tools to draw many different geometric shapes. Circles Triangles Rectangles Polygons Regular Polygons Graphs & Geometry 285 When you use a shape tool, the pointer becomes a pencil. As you create any shape that includes a linear portion (for example a ray, segment, or triangle), you can enable custom alignment. Align a linear portion of the shape to either the horizontal or the vertical axis. Press g to orient the linear portion of a shape in 15 degree increments relative to the x axis. For precise shape definition, you can type the coordinates of a shape?s defining points in parentheses instead of clicking. For example, to create a circle with a center point at (-1, 4) type (-1, 4) when prompted for the center point. On the work area, click once to establish the first vertex of the triangle. A dimmed representation of the shape or a partial shape displays to guide you. Click the work area again to establish the second point or complete the shape. You will need to move and position the pointer as many times as required for the shape you are drawing. You can move the pointer to the shape tool icon at the top of the work area to read tips for creating a shape. When all points or angles are in position, press to complete the shape. For example, you can move a shape around the work area, resize it, change its attributes, and pin it to the work area or an axis. You can explore and analyze shapes using tools such as the measurement or transformation tools. Sizing and positioning shapes 1. You can click and drag a circle?s perimeter to resize it, or click and drag a point to resize a polygon, rectangle, or triangle. Move a shape by grabbing and dragging the center point (circle) or a side (triangle, rectangle, or polygon). 288 Graphs & Geometry Identifying equations for circles and lines You can display the equation of any Analytic object (constructed in the Graphing View, or within the Analytic Window of the Plane Geometry View) and label it on the screen. The equation for the circle or line displays and the object blinks on the screen. Press to anchor the equation on the screen. Note: If you approach a defined point on the line or the center point of a circle, the coordinates for that point display instead of the equation. [. . . ] If selecting Handheld only, check Always in Front to keep this window on top of all other open applications. 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?emulator 607 When you open a document using the emulator, you can only open documents that are in the folder displayed on the emulator (usually the My Documents folder, unless you specified a different folder in your TI-SmartView?
