Rect to Polar, Polar to Rect
"Pol(" converts rectangular coordinates to polar coordinates, while "Rec("
converts polar coordinates to rectangular coordinates.
• Specify the Angle Unit on the SETTINGS menu before performing
calculations.
• The calculation result for r and θ and for x and y are each stored
respectively to variables x and y.
• Calculation result θ is displayed in the range of -180° < θ ≤ 180°.
Note
• Pol( and Rec( can be used on the calculation screen of the calculator apps below.

Example 1:
To convert rectangular coordinates (√2, √2) to polar
coordinates (Input/Output: MathI/MathO, Angle Unit: Degree)
– [Angle/Coord/Sexa] > [Rect to Polar]
Example 2:
To convert polar coordinates (√2, 45°) to rectangular
coordinates (Input/Output: MathI/MathO, Angle Unit: Degree)
– [Angle/Coord/Sexa] > [Polar to Rect]
