Chapter 6: Sequence Graphing

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.

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
