Polar[ <Point>, <Conic> ]
Creates the polar line of the given point relative to the conic section.
Example: Polar[(0,2), y = x^2 - 3x + 5] creates the line 1.5x + 0.5y = 4
Note: See also Mode polardiameter.svg Polar or Diameter Line tool.


and reverse of the previous :

Polar[<Line>, <Conic>]
Example: Polar[1.5x+0.5y=4, y = x^2 - 3x + 5] creates the point (0, 2)
