To change from the recursion formula screen, see "To change graph properties from the graph relation list screen" (page 5-15). To change from the graph screen, see "To change graph properties from the graph screen" (page 5-16). • After drawing a graph, you can use Trace, Zoom, and Sketch. • Press A to return to the number table screen. After drawing a graph, you can toggle between the number table screen and graph screen by pressing !6(G⇔T). k Graphing a Phase Plot from Two Numeric Sequences You can draw the phase plot for numeric sequences generated by two expressions input in the Recursion mode with one value on the horizontal axis and the other value on the vertical axis. For an (an+1, an+2), bn (bn+1, bn+2), cn (cn+1, cn+2), the numeric sequence of the alphabetically first expression is on the horizontal axis while the following numeric sequence is on the vertical axis. 1. From the Main Menu, enter the Recursion mode. 2. Configure V-Window settings. 3. Enter two recursion formulas and select both of them for table generation. 4. Configure table generation settings. Specify the start and end values for variable n and the initial term for each recursion formula. 5. Display the recursion formula number table. 6. Draw the phase plot. Example To input the two sequence formulas for regression between two terms an+1 = 0.9an and bn+1 = bn + 0.1n − 0.2, and specify initial terms a1 = 1 and b1 = 1 for each. Generate a number table as the value of the n variable goes from 1 to 10 and use it to draw a phase plot. Use the following V-Window settings. Xmin = 0, Xmax = 2, Xscale = 1 Ymin = 0, Ymax = 4, Yscale = 1 5-45
