3. Tap a point and press
E to see its polar
line.
4. Tap a line and press
E to see its pole.
In the illustration to the
right, point K is the
reciprocation of line DE
(G) and Line I (at the bottom of the display) is the
reciprocation of point H.
Cartesian
Abcissa Tap a point and press E to select it. The abscissa (x-
coordinate) of the point will appear at the top left of the
screen.
Ordinate Tap a point and press E to select it. The ordinate (y-
coordinate) of the point will appear at the top left of the

Coordinates Tap a point and press E to select it. The coordinates of
the point will appear at the top left of the screen.
Equation of Tap an object other than a point and press E to select
it. The equation of the object (in x and/or y) is displayed.
Parametric Tap an object other than a point and press E to select
it. The parametric equation of the object (x(t)+i*y(t)) is
displayed.
Polar
coordinates

coordinates of the point will appear at the top left of the
screen.
Measure
