31. The radius of curvature at the origin, which is the vertex of the parabola, is twice the focal length. 32. Furthermore, the corners of the posts are quite " sharp " : they have a quite-small radius of curvature . 33. Also, the radial distance " r " need not be related to the radius of curvature of the path. 34. This allows for a readout in both refractive power ( dioptres ) and radius of curvature ( millimeters ). 35. Australian Finns are universally white; the wool has superior length, softness, better radius of curvature and reduced prickle factor. 36. If is a parametrized curve in then the radius of curvature at each point of the curve,, is given by 37. Blue represents the first radius of curvature and red the second radius of curvature at the thinned and thickened locations. 38. Plotting such maps requires that one be able to draw arcs of circles with a very large radius of curvature . 39. On the right hand side ? is the density, v is the velocity, and R is the radius of curvature . 40. When parallel curves are constructed they will have cusps when the distance from the curve matches the radius of curvature .
