dual curve造句

• The set of all such points H forms the dual curve.
• Ginninderra Drive crosses the eastern reach of Lake Ginninderra over dual curved spans.
• The construction of the dual curve is the geometrical underpinning for the Legendre transformation in the context of Hamiltonian mechanics.
• The dual curve is a curve in the projective tangent space at the point, and the affine cone over this curve is the Monge cone.
• The dual curve construction works even if the curve is piecewise linear ( or piecewise differentiable, but the resulting map is degenerate ( if there are linear components ) or ill-defined ( if there are singular points ).
• Further, both curves have a reflectional symmetry, corresponding to the fact that symmetries of a projective space correspond to symmetries of the dual space, and that duality of curves is preserved by this, so dual curves have the same symmetry group.
