8-3 Polar Coordinate Graphs
After
you
change
from
the
REC
‘Mode
to
the
POL
Mode,
you
can use
the
unit
to
draw
polar
coordinate
graphs.
When
you
graph
a
built-in
function,
the
range
parameters
are
set
by
the
unit
automatically.
The
functions
that
can
be
graphed
in
the
POL
Mode
are
those
that
fit
the
following
format:
r=f()
Note
that
you
should

Use
the

Mode
to
draw

Do

or

Mode.
When

Graphing Manually:Entered Functi ions.
You
can
graph
manually
entered
functions
by
‘simply
pressing

and
then
entering
