Be able to apply the first and second derivative tests to analyze the monotonicity and concavity of a function. 能应用导数判定函数的单调性与凹性并利用渐近线协助绘制函数图形。
It was proved that the continuity and strict monotonicity of mappings in the variational model ensure the existence and uniqueness of equilibrium flows, respectively. 证明了变分模型中映射的连续性及严格单调性可分别保证均衡流量的存在性和唯一性。
