COORDINATE CONVERSIONS
A point on a circle can be described with rectangular coordinates
)
,
(
y
x
or
polar coordinates
)
,
(

r
, where
r
is the radius of the circle and

is the
angle counterclockwise for t
he positive x
-
axis.
Before converting, press
and then choose degrees,
radians, or grads. Use your EL
-
W516B to find the corresponding point on
the circle.
