Rectangular/polar coordinate conversion
This calculator is equipped with rectangular coordinates and polar
coordinates conversion capabilities.
x
Rectangular to polar coordinate conversion functions
Conversion formulas: r = (x
Polar to rectangular coordinate conversion functions
Conversion formulas: x = rcos θ , y = rsin θ
xy→r( x coordinate, y coordinate )
3 xy→r(
Returns polar coordinate radius
value from X-Y rectangular
coordinates.
4 xy→θ(
xy→θ( x coordinate, y coordinate )
Returns polar coordinate θ
value from X-Y rectangular
coordinates.
The following ranges are used to
find θ.
Degree mode: 0 ≤ |θ| ≤ 180
Radian mode: 0 ≤ |θ| ≤ 2π
Gradient mode: 0 ≤ |θ| ≤ 200
rθ→x( r coordinate , θ coordinate )
5 rθ→x(
Returns rectangular coordinate X
value from r-θ polar coordinates.
rθ→y(r coordinate, θ coordinate)
6 rθ→y(
Returns rectangular coordinate Y
value from r-θ polar coordinates.
