Properties & Relations  (6)

FromPolarCoordinates checks that inputs obey the normal restrictions of polar coordinates:

This point violates the condition on the angle :

Extract the symbolic transform from CoordinateTransformData to apply it to singular points:

FromPolarCoordinates preserves the shape of arrays:

This includes empty arrays:

FromPolarCoordinates[pt] is a special case of CoordinateTransform:

FromPolarCoordinates inverts ToPolarCoordinates:

FromPolarCoordinates[{x,y,z}] uses spherical coordinates about the axis:

FromSphericalCoordinates[{x,y,z}] uses spherical coordinates about the axis:

FromPolarCoordinates changes the coordinate values of points:

TransformedField changes the coordinate expressions for fields:
