k Rectangular-Polar Coordinate Conversion

Rectangular

Polar Coordinates

Coordinates (Rec)

(Pol)

•Coordinate conversion can be performed in the COMP and STAT calculation modes.

Converting to Polar Coordinates (Pol)

Pol(X, Y) X: Specifies the rectangular coordinate X value

Y:Specifies the rectangular coordinate Y value

•Calculation result θ is displayed in the range of –180°< θ <180°.

•Calculation result θ is displayed using the calculator’s default angle unit.

•Calculation result r is assigned to variable X, while θ is assigned to Y.

Converting to Rectangular Coordinates (Rec)

Rec(r,θ) r : Specifies r value of polar coordinate

θ: Specifies θ value of polar coordinate

•Input value θ is treated as an angle value, in accordance with the calculator’s default angle unit setting.

•Calculation result x is assigned to variable X, while y is assigned to Y.

•If you perform coordinate conversion inside of an expression instead of a stand-alone operation, the calculation is performed using only the first value (either the r-value or the X-value) produced by the conversion.

Example: Pol ('2, '2) + 5 = 2 + 5 = 7
