Using Calculation Modes
Technical Information
Rectangular-Polar Coordinate Conversion
Pol converts rectangular coordinates to polar coordinates, while Rec converts polar coordinates to rectangular coordinates.
(1) Rectangular Coordinates (Rec)
(2) Polar Coordinates (Pol)
Specify the angle unit before performing calculations.
Calculation result θ is displayed in the range of -180° < θ ≦ 180°.
Calculation results are automatically assigned to variables E and F. (fx-82MS/fx-85MS/fx-300MS/fx-350MS only)
Example 1: To convert polar coordinates (r = 2, θ = 60°) to rectangular coordinates (x, y) (Angle unit: Deg)
fx-82MS/fx-85MS/fx-300MS/fx-350MS:
-
x = 1
(Rec() 260 - 1.
-
y = 1.732050808
(F) - 1.732050808
Press (E) to display the value of x, or (F) to display the value of y.
fx-220 PLUS:
-
x = 1
2(,) 60 - 1.
-
y = 1.732050808
(y, θ) - 1.732050808
Press (x, r) to display the value of x, or (y, θ) to display the value of y.
Example 2: To convert rectangular coordinates (1, √3) to polar coordinates (r, θ) (Angle unit: Rad)
fx-82MS/fx-85MS/fx-300MS/fx-350MS:
-
r = 2
13 - 2.
-
θ = 1.047197551
(F) - 1.047197551
Press (E) to display the value of r, or (F) to display the value of θ.
fx-220 PLUS:
-
r = 2
1(,)3 - 2.
-
θ = 1.047197551
(y, θ) - 1.047197551
Press (x, r) to display the value of r, or (y, θ) to display the value of θ.
