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) + 5 = 2 + 5 = 7
