(2) Select "AX2 + BXY + CY2 + DX + EY + F = 0" 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: A = 1, B = 4, C = 1, D = ­6, E = 6, F = 4. (4) Tap ^ to graph the equation. 20021201 4-4-1 Using Trace to Read Graph Coordinates 4-4 Using Trace to Read Graph Coordinates Trace allows you move a pointer along a graph line and display the coordinates at the current pointer location. Starting the trace operation causes a crosshair pointer ( ) to appear on the graph. You can then press the cursor key or tap the graph controller arrows to move the pointer to the location you want, and read the coordinates that appear on the display. Using Trace Example: To graph the function x = 2(y ­ 1)2 ­ 2 and then perform a trace operation to read coordinates u ClassPad Operation (1) On the Conics Editor window, input the above equation and then tap ^ to graph it. (2) Tap [Analysis] and then [Trace], or tap =. · This causes "Trace" to appear on the Graph window, with a pointer on the graph line. (3) Press the left or right cursor key, or tap the left or right graph controller arrows.
