To change from the recursion formula screen, see “To change graphproperties 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 togglebetween the number table screen and graph screen by pressing !6(G⇔T).k Graphing a Phase Plot from Two Numeric SequencesYou can draw the phase plot for numeric sequences generated by two expressions input inthe Recursion mode with one value on the horizontal axis and the other value on the verticalaxis. For an (a n+1, an+2 ), bn (bn+1 , b n+2), cn (cn+1, cn+2), the numeric sequence of the alphabeticallyfirst expression is on the horizontal axis while the following numeric sequence is on the verticalaxis.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 recursionformula.5. Display the recursion formula number table.6. Draw the phase plot.Example To input the two sequence formulas for regression between two termsa n+1 = 0.9a n and b n+1 = b n + 0.1n − 0.2, and specify initial terms a1 = 1 andb1 = 1 for each. Generate a number table as the value of the n variablegoes from 1 to 10 and use it to draw a phase plot.Use the following V-Window settings.Xmin = 0, Xmax = 2, Xscale = 1Ymin = 0, Ymax = 4, Yscale = 1
