Example To draw the WEB graph for the recursion formula
a n+1 = –3( a n)
2
+ 3 a n,
b n+1 = 3 b n + 0.2, and check for divergence or convergence. Use the
following table range and V-Window settings.
Table Range
Start = 0, End = 6,
a 0 = 0.01, a nStr = 0.01, b 0 = 0.11, b nStr = 0.11
V-Window Settings
Xmin = 0, Xmax = 1, Xscale = 1
Ymin = 0, Ymax = 1, Yscale = 1
