TI-83 Plus Sequence Graphing 191
ZOOM
ZOOM operations in Seq graphing work the same as in Func graphing.
Only the X (Xmin, Xmax, and Xscl) and Y (Ymin, Ymax, and Yscl) window
variables are affected.
PlotStart, PlotStep,
n
Min, and
n
Max are only affected when you select
ZStandard. The VARS Zoom secondary menu ZU items 1 through 7 are the
ZOOM MEMORY variables for Seq graphing.
CALC
The only CALC operation available in Seq graphing is value.
• When Time axes format is selected, value displays Y (the u(
n
) value)
for a specified
n
value.
• When Web axes format is selected, value draws the web and displays
Y (the u(
n
) value) for a specified
n
value.
• When uv, vw, or uw axes format is selected, value displays X and Y
according to the axes format setting. For example, for uv axes format,
X represents u(
n
) and Y represents v(
n
).
