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).

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 .

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