COORDINATE CONVERSIONS

Apoint on a circle can be described with rectangular coordinates (x, y) 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.

1.While in degrees convert the rectangular coordinates (2,2) to polar coordinates (r, ) .
