variables define the viewing window. The values below are
defaults for
Seq
graphing in both
Radian
and
Degree
angle
modes.
n
Min=1
Smallest
n
value to evaluate
n
Max
=
10
Largest
n
value to evaluate
PlotStart
=
1
First term number to be plotted
PlotStep
=
1
Incremental
n
value (for graphing only)
Xmin
=
L
10
Smallest
X
value to be displayed
Xmax
=
10
Largest
X
value to be displayed
Xscl
=
1
Spacing between the
X
tick marks
Ymin
=
L
10
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.
