uTo modify a graph in the Conic Graphs mode

Example	In the Conic Graphs mode, register the parametric equation X = H + T ;
	Y = K + AT2 and the initial values A=2, H=0, K=0. Next, use the Modify
	function to change H to −1 and then change K to −1, and observe the
	changes in the graph.

1.From the Main Menu, enter the Conic Graphs mode.

2.Press 3(PARAM) to display the parametric equation list.

3.Use c to move the highlighting to X = H + T ; Y = K + AT2 and then press w.

• This will display a coefficients input screen.

4.Perform the following key operation to input A=2, H=0, K=0. cwawaw

5.Press 1(MODIFY) to execute the Modify function.

6. Press c. Check to make sure that the H=0 line is magenta colored and then press d.
