ToPolarCoordinates

ToPolarCoordinates[{x,y}]

gives the {r,θ} polar coordinates corresponding to the Cartesian coordinates {x,y}.

ToPolarCoordinates[{x1,x2,…,xn}]

gives the hyperspherical coordinates corresponding to the Cartesian coordinates {x1,x2,…,xn}.

Details

  • ToPolarCoordinates produces points in the standard range , in two dimensions, and , , in higher dimensions.
  • ToPolarCoordinates automatically threads over arrays of coordinate lists.
