Pol(
On a Casio calculator you can convert rectangular coordinates (x, y) to polar coordinates (r, θ)
▷ ANGL ▷ Pol( OPTN F6 F5 F6 F1
or via the catalog as
CATALOG P
INPUT SHIFT 4 Pol( F1
Example 1
To convert cartesian coordinates (x = 1, y = √3) to polar coordinates (r = 2, θ = 60°)
Pol( √ r ≣ Pol( 1 ٬ SHIFT x² 3 ) EXE Pol(1,√3) {2,60}
where the right parentheses is not really necessary.
Example 2
To convert rectangular coordinates (1, 1.739) to polar coordinates (r, θ)
Pol( ≣ 1 ٬ 1 · 7 3 9 EXE Pol(1,1.739) {2.006021186,1.04892▷
and show the rest of θ
