To display the window variables, press p. These
variables define the viewing window. The values below are
defaults for
Seq graphing in both Radian and Degree angle
modes.
nMin=1 Smallest n value to evaluate
nMax=10 Largest n value to evaluate
PlotStart=1 First term number to be plotted
PlotStep=1 Incremental n value (for graphing only)
Xmin=L10 Smallest X value to be displayed
Xmax=10 Largest X value to be displayed
Xscl=1 Spacing between the X tick marks
Ymin=L10 Smallest Y value to be displayed
Ymax=10 Largest Y value to be displayed
Yscl=1 Spacing between the Y tick marks
nMin must be an integer ‚ 0. nMax, PlotStart, and PlotStep
must be integers ‚ 1.
nMin is the smallest n value to evaluate. nMin also is displayed
in the sequence
Y= editor. nMax is the largest n value to
evaluate. Sequences are evaluated at
u(nMin), u(nMin+1),
u(nMin+2) , . . . , u(nMax).
PlotStart is the first term to be plotted. PlotStart=1 begins
plotting on the first term in the sequence. If you want plotting to
begin with the fifth term in a sequence, for example, set
PlotStart=5. The first four terms are evaluated but are not
plotted on the graph.
PlotStep is the incremental n value for graphing only. PlotStep
does not affect sequence evaluation; it only designates which
points are plotted on the graph. If you specify
PlotStep=2, the
sequence is evaluated at each consecutive integer, but it is
plotted on the graph only at every other integer.
