1.设曲线L是上半圆周x2+y2=2x,则xdl=π L 解法1由于L关于直线x=1对称,所以∫(x-1)dl=0,从而 L xdl=f[(x-1)+1l=f(x-1)dl+fdl=0+π=π L L L =1+ cost, 解法2令L:y=sint (0≤t≤),则 xdl =Jo (+cost)(-sint)2+(cost)dt=. L 解法3设曲线L的质量分布均匀,则其重心的横坐标为x=1又因为 ∫xdl xdl x= d 1么 π 所以∫xdl=π。 L 2.设L是上半椭圆周x2+4y2=1,y≥0,是四分之一椭圆周 x2+4y2=1,x≥0,y≥0,则 (A)(+ y) (+y) (B) Ixydl =2J, xydl () SLx2dl, y2dl (D)(x+y)2dl =2J (x2+y2) [] 答D

Measuring the Cost of Living Inflation refers to a situation in which the economy’s overall price level is rising.(通货膨胀指经济的总体 物价水平上涨) The inflation rate is the percentage change in the price level from the previous period

Capital cost projects begin when a need is defined that cannot be satisfied in existing facilities. Thus begins the life cycle of a capital project (Fig. 1). Once started, the project will progress through all of the following phases or be canceled. It all starts with the recognition of a need that will require capital plant. In the conceptual phase of the project, multiple approaches will be evaluated and one or more plans will be evaluated for meeting these needs

Optimal Routing View routing as\global\ optimization problem Assumptions: The cost of using a link is a function of the flow on that link The total network cost is the sum of the link costs The required traffic rate between each source-destination pair is known in advance Traffic between source-destination pair can be split along multiple paths with infinite precision

Once a company determines its fixed and variable costs, it can then conduct cost-volume-profit analysis Basically, CVP analysis explores the relationships among costs, volume or activity levels, and profit Break-Even Point One of the primary uses of CVP analysis is to calculate the break-even point. The break-even-point is the number of units
