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=1First term number to be plotted
PlotStep=1Incremental
n
value (for graphing only)
Xmin=L10 Smallest X value to be displayed
Xmax=10 Largest X value to be displayed
Xscl=1Spacing between the X tick marks
Ymin=L10 Smallest Y value to be displayed
Ymax=10 Largest Y value to be displayed
Yscl=1Spacing between the Y tick marks
n
Min must be an integer ‚ 0.
n
Max, PlotStart, and PlotStep
must be integers ‚ 1.
n
Min is the smallest
n
value to evaluate.
n
Min also is
displayed in the sequence Y= editor.
n
Max is the largest
n
value to evaluate. Sequences are evaluated at u(
n
Min),
u(
n
Min+1), u(
n
Min+2) , . . . , u(
n
Max).
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.
