[. . . ] 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: · Reorient or relocate the receiving antenna. · Increase the separation between the equipment and receiver. · Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. [. . . ] · This displays the Select Conics Form dialog box. (2) Select "(X ­ H)2 + (Y ­ K)2 = R2 " and then tap [OK]. · This closes the Select Conics Form dialog box, and displays the selected equation in the Conics Editor window. (3) Change the coefficients of the equation as follows: H = 2, K = 1, R = 2. (4) Tap ^ to graph the equation. 20021201 4-3-5 Drawing a Conics Graph k Drawing a Circle by Specifying the Coefficients of a General Equation Example: To draw the circle x2 + y2 + 4x ­ 6y + 9 = 0 u ClassPad Operation (1) In step (2) of the procedure under "Drawing a Circle by Specifying a Center Point and Radius", select "AX2 + AY2 + BX + CY + D = 0". (2) Substitute the following values for the coefficients: A = 1, B = 4, C = ­6, D = 9. Drawing an Ellipse You can draw an ellipse by specifying coefficients for the standard equation: (x ­ H)2 (y ­ K)2 + = 1. A2 B2 (x ­ 1)2 (y ­ 2)2 Example: To draw the ellipse + =1 32 22 u ClassPad Operation (1) On the Conics Editor window, tap q, or tap [Form] and then [Insert Conics Form]. · This displays the Select Conics Form dialog box. (2) Select " (X ­ H)2 (Y ­ K)2 + = 1" and then tap [OK]. A2 B2 · This closes the Select Conics Form dialog box, and displays the selected equation in the Conics Editor window. (3) Change the coefficients of the equation as follows: A = 2, B = 3, H = 1, K = 2. (4) Tap ^ to graph the equation. 20021201 4-3-6 Drawing a Conics Graph Drawing a Hyperbola A hyperbola can be drawn with either a horizontal or vertical orientation. Input values into the message box and then tap [OK]. Here, input a value for yc in the case of a parabola that opens horizontally. Input a value for xc in the case of a parabola that opens vertically. For any other type of conics graph, input a value for tc in order to graph in parametric format. (4) To exit trace, tap on the icon panel. Tip · While tracing, tapping the displayed coordinate values causes the coordinate values to appear in the message box. You can then copy the coordinates to the clipboard. 20021201 4-5-1 Using G-Solve to Analyze a Conics Graph 4-5 Using G-Solve to Analyze a Conics Graph The G-Solve menu includes commands that let you perform a variety of different analytical processes on a graph drawn on the Conics Graph window. Displaying the G-Solve Menu While there is a graph on the Conics Graph window, tap [Analysis] and then [G-Solve]. You can then use the [G-Solve] menu that appears to perform one of the operations described below. To obtain this: Focus of a parabola, ellipse, or hyperbola Vertex of a parabola, ellipse, or hyperbola Directrix of a parabola Axis of symmetry of a parabola Length of the latus rectum of a parabola Center point of a circle, ellipse, or hyperbola Radius of a circle Asymptotes of a hyperbola Eccentricity of a parabola, ellipse, or hyperbola Select this [G-Solve] menu item: Focus Vertex Directrix Symmetry Length of Latus Rectum Center Radius Asymptotes Eccentricity x-Intercept y-Intercept x-intercept y-intercept x-coordinate for a given y-coordinate y-coordinate for a given x-coordinate x-Cal y-Cal Tip · Some commands are available only for certain types of graphs. Any command that is not available for the graph currently displayed on the Conics Graph window has a line through it. A parabola, for example, does not have a center, radius or asymptotes, so there are lines through the [Center], [Radius], and [Asymptotes] commands of the [G-Solve] menu when there is a parabola on the Conics Graph window. 20021201 4-5-2 Using G-Solve to Analyze a Conics Graph Using G-Solve Menu Commands The following are some examples of how to perform the Conics application [G-Solve] menu commands. u To determine the focus of the parabola x = 2(y ­ 1)2 ­ 2 (1) On the Conics Editor window, input the conics equation and then tap ^ to graph it. · Here, input the parabolic equation x = 2(y ­1)2 ­ 2.
