Angle Unit, Polar/Rectangular
Coordinate, Sexagesimal
This section explains commands, functions, and symbols that you can
input after performing the operation:
– [Angle/Coord/Sexa].
Degrees, Radians, Gradians
These functions specify the angle unit.
° specifies degree,
r
radian, and
g
gradian.
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)
(π) 2
– [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°.
Note
• Pol( and Rec( can be used on the calculation screen of the calculator apps below.•
