摘要
总结有关多元函数微分学中六个重要概念的关系,并通过二元函数具体的实例详细加以证明,建立它们之间的关系图。对有效的理解和掌握多元微分起到重要作用。
This thesis is mainly talking about the relationships among the six important concepts in the multivariate differential and integral calculus, and through using the concrete examples of bivariate function to demonstrate how they are related and show their relationship diagrams. This thesis is of great help to apprehend and master the multivariate differential and integral calculus.
