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
