Example Generate a number table from recursion between three terms as expressed by an+2 = an+1 + an, with initial terms of a1 = 1, a2 = 1 (Fibonacci sequence), as n changes in value from 1 to 6. 1 m Recursion 2 3(TYPE)3(an+2) 3 4(n.an ··)3(an+1)+2(an)w 4 5(SET)2(a1)bwgwbwbwJ 5 6(TABLE) * The first two values correspond to a1 = 1 and a2 = 1. • Pressing 1(FORMULA) will return to the screen for storing recursion formulas. • Specifying "On" for the "ΣDisplay" of the Setup screen causes the sum of each term to be included in the table. k Graphing a Recursion Formula After generating a number table from a recursion formula, you can graph the values on a line graph or plot type graph. 1. From the Main Menu, enter the Recursion mode. 2. Configure V-Window settings. 3. Specify the recursion formula type and input the formula. 4. Specify the table range, and start and ending values for n. If necessary, specify the initial term value and pointer start point. 5. Select the line style for the graph. 6. Display the recursion formula number table. 7. Specify the graph type and draw the graph. 5(GPH-CON) ... line graph 6(GPH-PLT) ... plot type graph Example Generate a number table from recursion between two terms as expressed by an+1 = 2an + 1, with an initial term of a1 = 1, as n changes in value from 1 to 6. Use the table values to draw a line graph. Use the following V-Window settings. Xmin = 0, Xmax = 6, Xscale = 1 Ymin = -15, Ymax = 65, Yscale = 5 5-44
