Pol(
On a Casio calculator you can convert rectangular coordinates (x, y) to polar coordinates (r, θ)
Pol(
Calculation results are automatically assigned to variables E and F.
Example 1
To convert cartesian coordinates (x = 1, y = √3) to polar coordinates (r = 2, θ = 60°)
Pol(1,√3)
2.Pol( 1 ٬ √ 3 ) =
and show the value r = 2 from variable E
cos⁻¹ E E=
2.RCL cos
and show the value θ = 60° from variable F
tan⁻¹ F F=
60.RCL tan
Example 2
To convert rectangular coordinates (1, 1.739) to polar coordinates (r, θ)
Pol(1,1.739)➞
2.006021186Pol( 1 ٬ 1 · 7 3 9 ) =
and show the value of θ from variable F
tan⁻¹ F F=
1.048929636RCL tan
Example 3
The right parentheses is not really necessary, so you can just enter
