k Rectangular-Polar Coordinate Conversion
Rectangular Polar Coordinates
Coordinates (Rec) (Pol)
•Coordinate conversion can be performed in the COMP and STAT
calculation modes.
Converting to Polar Coordinates (Pol)
Pol(X, Y) X: Specifies the rectangular coordinate X value
Y: Specifies the rectangular coordinate Y value
•Calculation result
θ
is displayed in the range of –180° <
θ
< 180°.
•Calculation result
θ
is displayed using the calculator’s default angle
unit.
•Calculation result r is assigned to variable X, while
θ
is assigned
to Y.
Converting to Rectangular Coordinates (Rec)
Rec(r,
θ
) r : Specifies r value of polar coordinate
θ
:Specifies
θ
value of polar coordinate
• Input value
θ
is treated as an angle value, in accordance with the
calculator’s default angle unit setting.
•Calculation result x is assigned to variable X, while y is assigned
to Y.
• If you perform coordinate conversion inside of an expression instead
of a stand-alone operation, the calculation is performed using only
the first value (either the r-value or the X-value) produced by the
conversion.
Example: Pol ('2, '2) + 5 = 2 + 5 = 7
