Displaying a Graph
When you press
s
, the TI
.
82 plots the selected polar equations. It
evaluates
R
for each value of
q
(from
q
min
to
q
max
in intervals of
q
step
)
and then plots each point.
As a graph is plotted, the TI
.
82 updates
X
,
Y
,
R
, and
q
.
Smart Graph applies to polar graphs.
Note that the free-moving cursor displays
X
and
Y
coordinate values if the
WINDOW FORMAT
setting is the default
RectGC
. To see
R
and
q
, select
