在现代经济管理中,有许多最优化问题属于多元函 数的极值和最值问题同一元函数类似,其最值也与其极 值有十分密切的联系;故以下以二元函数为例用多元函 数微分法先来讨论多元函数的极值,再讨论多元函数的 最值. 多元函数极值问题有两种基本类型(以二元函数为例) 类型I:讨论z=f(xy)的极值——无条件极值 类型Ⅱ:讨论z=f(xy)在约束条件(xy)=0下的极值 条件极值

碰撞两物体互相接触时间极短而互作用力较大 的相互作用.∵Fx<=C i 完全弹性碰撞两物体碰撞之后,它们的动能之 和不变E=E1+E2=C 非弹性碰撞由于非保守力的作用,两物体碰撞后,使机械能转换为热能、声能,化学能等其他形式的能量
