摘要
通过分析,给出切线和切平面量化定义的等价形式,结合对二元函数的可微性的研究,得到求曲面的切线和切平面的简便方法.
Through the analysis of the quantified definition of tangent line and tangent plane,gave the equivalent form of the quantified definition of tangent line and tangent plane.According to the differenability of a binary function,obtained method for seek tangent line and tangent plane.
