Angle Unit, Polar/Rectangular
Coordinate, Sexagesimal
This section explains commands, functions, and symbols that you can
input after performing the operation:

Degrees, Radians, Gradians

These functions specify the angle unit.
r
° specifies degree,
You can input each function using the menu items below.
– [Angle/Coord/Sexa] > [Degrees]
– [Angle/Coord/Sexa] > [Radians]
– [Angle/Coord/Sexa] > [Gradians]
Example: π/2 radians = 90° (Angle Unit: Degree)
– [Angle/Coord/Sexa] > [Radians]

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°.
