u u u u u Rectangular Coordinates

• With polar coordinates, θ can be calculated and displayed within a range of

–180°< θ < 180° (radians and grads have same range).

• Be sure to specify "Comp" for Calculation/binary, octal, decimal, hexadecimal

mode.

Example

To calculate r and θ

Operation

Example

To calculate x and y when r = 25 and θ = 56

Operation
