Sequence Graphing 352
3. Moves horizontally to the y=x reference line.
4. Repeats this vertical and horizontal movement until
n=nmax.
Note: The web starts at plotstrt. The value of n is incremented by 1 each time the web
moves to the sequence (
plotStep is ignored).
Example: Convergence
1. On the Y= Editor (8#), define u1(n) = L.8u1(nN1) + 3.6. Set initial value ui1 = L4.
2. Set
Axes = TIME.
3. On the Window Editor (8$), set the Window variables.
5. On the Y= Editor, set
Axes = WEB and Build Web = AUTO.
nmin=1
nmax=25
plotstrt=1

4. Graph the sequence (8%).
By default, a sequence uses the
Square display style.
