第七章定积分 The definite integration 习题讨论 题目: ayx-b 1,计算1= -dx. (x-b)2+a2 2,计算m=(n)dx,其中n,m为自然数。 0 3,计算J=1 --dx,其中x是x的整数部分。 sinx sinx 4,一研究1= (+,= dx,p>0的敛散性 +sinx 解答: aypx-b

1 a) In an M&M frictionless environment, where there are no taxes and contracts are costless to make and enforce, the wealth of the shareholder is the same no matter what capital structure the firm adopts. In such an environment, neither the stock price nor shareholders' wealth would be affected

例1证明:向量组a1(≠0),a2,…,a线性 相关的充分必要条件是其中至少有一个a,1
