Example To draw the WEB graph for the recursion formula an+1 = -3(an)2 + 3an, bn+1 = 3bn + 0.2, and check for divergence or convergence. Use the following table range: Start = 0, End = 6, a0 = 0.01, anStr = 0.01, b0 = 0.11, bnStr = 0.11 1 m Recursion 2 !3(V-WIN)awbwbwc awbwbwJ 3 3(TYPE)2(an+1)-d2(an)x+d2(an)w d3(bn)+a.cw 4 5(SET)1(a0) awgwa.abwa.bbwc a.abwa.bbwJ 5 6(TABLE) 6 4(WEB-GPH) 7 w~w(an is convergence) cw~w(bn is divergence) • To change the graph line style, press 1(SEL+S) after step 4. • With WEB Graph, you can specify the line type for a y = f(x) graph. The line type setting is valid only when "Connect" is selected for "Draw Type" on the Setup screen. 11. Graphing a Conic Section k Graphing a Conic Section You can use the Conic Graphs mode to graph parabolas, circles, ellipses, and hyperbolas. You can input a rectangular coordinate function, polar coordinate function, or parametric function for graphing. 1. From the Main Menu, enter the Conic Graphs mode. 2. Select the function type. 1(RECT).... {rectangular coordinate} 2(POL).... {polar coordinate} 3(PARAM).... {parametric} 5-48
