Groups. Teams and Effectiveness oGroup: two or more people who interact with each other to accomplish a goal. oTeam: group who work intensively with each other to achieve a specific common goal All teams are groups, BUT, not all groups are teams. o Teams often are difficult to form I Takes time for members to work together. Teams can improve organizational performance Irwin/McGraw-Hill

1、据基数效用论的消费均衡条件若M1≠M2,消费者应如何调整两种 A P 商品的购买量?为什么?若≠,i=1、2有应如何调整?为什么?

证明若干个命题等价的一般方法 本节证明七个实数基本定理等价性的路线:证明按以下三条路线进行 I:确界原理→单调有界原理→区间套定理→ Cauchy收敛准则

一、微元法 b 定积分f(x)dx是和式的极限lim∑f(5)△x,如果所研究的 →0 a i= 问题总可以按“分割、近似求和与取极限”三个步骤能归结为求这 种和式的极限,那么,应用定积分就可以求出问题的结果

特勒根定理1: 对于一个具有n个结点、b条支路的网络,假设各支 路电压(u)和支路电流(i)取关联参考方向, 则有: =0 物理意义:各支路吸收的功率之和等于零

NOTE: On the“ ethics” of problem sets Some of the theoretical exercise I will assign are actually well-known results; in other cases you may be able to find the answer in the literature. This is certainly the case for the current My position on this issue is that, basically, if you look up the answer somewhere it's your problem. After all, you can buy answer keys to most textbooks. The fact is, you will not have access to such, ehm, supporting material when you take your generals, or, in a more

12-3二阶电路的阶跃响应和冲激响应 一、阶跃响应 例:电路如图。已知)=0,i(0)=0,R=2

14-1状态、状态变量及状态方程 一、状态 在某给定时刻,电路所必须具备的最少量的信息。 二、状态变量 如电容电压uc,电感电流i 三、状态方程 状态方程:以状态变量为未知量而建立的一阶微分方程组
