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-W535B to find the corresponding point on the
circle.
