Use in VB API Dynamic drawing, including sine, cosine, tangent, Cotangent, can also modify the code-defined functions.

在VB中利用API实现动态画图，包括正弦，余弦，正切，余切等，也可以通过修改代码自定义函数。

More precisely, we obtain an important relation between the mapping Ψ, which plays an important role in defining obstruction set, and the mapping on the cotangent bundle induced by the original diffeomorphism. We show that the only difference between them is a nonlinear factor.

在§3.2中我们得到了在定义阻碍集这一概念中起着关键作用的Ψ映射与原来映射在其余切丛上所诱导映射之间仅仅只相差一个非线性因子这一重要关系。

This code is not casually arranged, it actually represents the Frog Kok of Cotangent value, which is part of Frog heart right triangle and two right-angle-FE AE ratio, that is, N = ctg α= FE / AE , N, is turnout.

这个代号可不是随便排列的，它实际上代表了辙叉角的余切值，也就是辙叉心部分直角三角形两条直角边FE和AE的比值，即N=ctgα=FE/AE，N就是道岔号。

The definitions of generalized directional derivative and generalized gradient of Lipschitz functions defined on Riemannian manifold are presented. Some properties of the directional derivative and gradient are proved by using tangent and cotangent mapping. The minimization necessary condition of nonsmooth Lipschitz functions is given. Moreover, Fritz John necessary optimality condition in mathematical programming is provided on Riemannian manifold.
