Note
• The following cannot be used in f(x): Pol, Rec, ÷R. The following cannot be used in
f(x), a, or b: ∫, d/dx, Σ.
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.
The calculation result for r and θ and for x and y are each assigned
respectively to variables X and Y.
Calculation result θ is displayed in the range of -180° < θ ≦ 180°.
Example 1: To convert rectangular coordinates (√
2; √2) to polar
coordinates (Angle unit: Deg)
(MthIO-MathO)
(Pol) 2 (;) 2
r = 2; θ = 45
(LineIO)
(Pol) 2 (;) 2
r = 2
θ = 45
Example 2: To convert polar coordinates (√2; 45°) to rectangular
coordinates (Angle unit: Deg)
