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 the 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.
