Standard values (set when you select

6:ZoomStd

from the

Zoom

toolbar menu) are:

You may need to change the standard values for the n and plot variables to ensure that
sufficient points are plotted.

To see how

plotstrt

affects graph, look at the following examples of a recursive

sequence.

Note:

Both of these graphs use the same Window variables, except for

plotstrt

.

nmin = 1.
nmax = 10.
plotstrt = 1.
plotstep = 1.

xmin =

L

10.

xmax = 10.
xscl = 1.

ymin =

L

10.

ymax = 10.
yscl = 1.

This graph is plotted beginning with the 1st term.

This graph is plotted beginning with the 9th term.
