class ConicPolar
constructors: |
|
---|---|
returns: | the polar of the point with respect to the conic, if chord=true then the line.p1 and line.p2 are the points of intersection of the polar and the conic |

---|---|
returns: | the polar of the given point with the respect to the given circle. if keyword chord=True, the line p1 and p2 are the points on circle of lines through point argument tangent to the circle |
condition: | point and circle are coplanar |
else returns: | None |
site ref: |
class LinePerp
