When we observed the graph being plotted, you'll notice that the graph is
not very smooth. That is because the plotter is using a time step that is too
large. To refine the graph and make it smoother, use a step of 0.1. Try the
following keystrokes:
@CANCL
˜˜˜.1
@@@OK@@@ @ERASE @DRAW
. The plot
will take longer to be completed, but the shape is definitely smoother than
before.

L
@LABEL @MENU
, to see axes labels and range. Notice that the
labels for the axes are shown as 0 (horizontal) and 1 (vertical). These are
the definitions for the axes as given in the PLOT WINDOW screen (see
above), i.e.,
H-VAR (t): 0
, and
V-VAR(x): 1
.
