空间曲线的切线向量求法

Law of Asking theTangent Vector of the Space Curve

空间曲线的数学表示形式有多种,而不同的表示形式,求其切线向量的方法也不同。本文就工程实际中可能出现的几种空间曲线的数学表示形式,分析其切线向量的求法。

The mathematical representations of space curve in mathematics have many forms, and the means by which to get the tangent vector varies according to the various representations. There are some mathematical representations of space curves which will probably be met in actual engineering, and this article discusses how to get the tangent vector of these space curves according to their various mathematical representations.
