Curvature of a Plane Curve Definition: If T is the unit vector of a smooth curve, the curvature function of the curve is κ=|dTds|. 曲率的意义是曲线扭曲的程度,如图,直线“不曲”,因此曲率为0. 曲率越大,曲线就越弯。 曲率的计算方法:一般情况下,用定义是不方便计算 κ 的值的,所以我们找一...
Curvature of Plane CurvesLet C = f−1(c), where f: U → ℝ, be a plane curve in the open set U ⊂ ℝ2, oriented by N = ∇f/∥∇f∥. Then, for each p ∈ C. the Weingartcn map Lp, is a linear transformation on the 1-dimensional spacc Cp....
