tangent plane of quadratic surface
where are constants and at least one of the six first is distinct from zero. The equation of the tangent plane of the surface, with as the point of tangency, is
This is said to be obtained from (1) by polarizing it.
Example. The tangent plane of the elliptic paraboloid set in the point of the surface is , and especially in the point it is .
