Say that the shaded in plane is the plane 
, and the polar grid we drew on it is our usual polar grid, with concentric circles that have positive integer radii starting at 
and consecutive rays through the origin that have an angle of 
between them:If the cylindrical coordinates of

where 
and 
are positive and
