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 Appendix to E-29
