[. . . ] If you need to delete a portion of the function, remove the unneeded characters and type any new characters. Press to graph the revised function. Hiding a Function on the Work Area 1. To redisplay hidden objects, repeat the steps above. 276 Graphs & Geometry Deleting a Function 1. The function is removed from the work area and from the list of graphed functions. Manipulating Functions Some functions allow you to translate, stretch and/or rotate them by grabbing and manipulating the graph. From the Actions menu, click Pointer, and then move to the graph that you want to manipulate. The pointer changes to indicate supported manipulation (for example, to , or ) when you hover on a graphed function that you can grab and manipulate. Graphs & Geometry 277 As you change the graph, the expression for the graph updates to reflect changes. Linear function; y=b Linear function; y=ax+b Quadratic function; y=a(x-b)2+c Quadratic function; y=ax2+bx+c Exponential function; y=exp(ax+b)+c Exponential function; y=b*exp(ax)+c Exponential function; y=d*exp(ax+b)+c Logarithmic function; y=a*ln(cx+b)+d Sinusoidal function; y=a*sin(cx+b)+d Cosinusoidal function; y=a*cos(cx+b)+d 278 Graphs & Geometry Manipulating a Linear Function Initial function graph Function translated along the x-axis. (Notice the revised function label) To translate, grab near the middle of the graph, and then drag. Manually rotated function. To rotate, grab and drag near the ends of the graph. Graphs & Geometry 279 Manipulating a Quadratic Function Original quadratic function Manually rotated function. To stretch, grab away from the vertex of the graph, and then drag. Function translated on the x-axis Function translated on the y- To translate, grab and drag near the vertex of the graph. 280 Graphs & Geometry Manipulating a Sine or Cosine Function Original sine function Rotation manipulation of the sine function. To stretch, grab away from the axis of vertical symmetry of the graph, and then drag. Translation manipulation along the y-axis. Translation manipulation along the x-axis. To translate, grab and drag near the axis of vertical symmetry of the graph. Finding the Derivative at a Point (the Slope) This method uses the Analyse Graph menu. Alternatively, you could create a tangent on the graph to help visualize the slope and then use the Measurement menu to measure it. Click the point on the graph at which you want to find the derivative. The value of the derivative at the selected point is displayed on the graph. Graphs & Geometry 281 Note: To find the derivative at a specific value of x or y, use the context menu of the point to show its coordinates, and then edit the x or y coordinate. Viewing Function Tables You can show a table of function values for any function in the current problem. While viewing the table, you can change the settings for the table, delete columns, add values for multiple functions, and edit the expression that defines a function. For more information, see Using Lists & Spreadsheet. Showing the Table ?The table is displayed in a split screen, showing columns of values for the currently defined functions. At the top of each column, you can choose the function to display in the column. 282 Graphs & Geometry Hiding the Table ?Click in the Graphs & Geometry window to display its menu, and then click Hide Table on the View menu. Using the Plane Geometry View The plane geometry view includes a scale by default, but includes no axes or entry line on the work area. Change to Plane Geometry View from the View menu by selecting Plane Geometry View. 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. Note: Any geometric constructions created while in the Plane Geometry View are retained and displayed along with any previously created graphs. Creating an Object in Plane Geometry View You can choose Geometry on an empty page of a document to work in Plane Geometry View.
