摘要
对高等数学和数学分析中二元函数可微的充分条件进行了研究,将条件减弱,得到了新的二元函数可微的充分条件,它揭示了二元函数偏导数存在与可微性之间的关系,并通过实例说明了函数可微的判定方法。
The sufficient conditions for binary function differentiation in advanced mathematics and mathematical analysis are studied. With the conditions weakened, obtains the condition of a new binary function differentiation, which reveals the relationship between binary function partial derivatives and differentiability. And illustrates the differentiability of function with examples.
