摘要
Abstract
Counter examples are preferred than theoretical argumentation in proving some false propositions or relational expressions in higher mathematics. Employing counter examples, this paper first illustrates some false propositions and relational expressions in multivariate function and then demonstrates that the properties from u-nivariate function to multivariate function conform to the change from quantitative to qualitative.关键词
