however,see the current problems as merely part of an evolutionary process.They arguethat London and New York had similar problems but were able eventually to establish an orderly and safe environment

they have;the real culture is the culture they actually have.In all societies there is a differencebetween the two.If an American citizen were asked to tell a visitor from a foreign land something about how Americans think and live,his description would probably be somewhat less than true.He might say,for example,that the United States is a democracy(民主),that all men are created equal,and that

0,f(0) = 1,f(1) = e,f(2) = e,∫f(2x)dx = 1/2ex,则 f'(0) = 1/25.已知 f(x) = (1+x^2)/(1+x),则 f'(0) = 1二、单项选择(每小题3分,满分15分)1.函数 f(x) = x*sinx,则 B 选项为正确答案,即当x → ±∞ 时有极限。

2.已知 f(x) = { e^x。

x < 1.ln x。

x ≥ 1 },则 f(x) 在 x = 1 处的导数不存在,答案为 D。

3.曲线 y = xe^(-x^2) 的拐点是 (1/e。

1/(2e)),答案为 C。

4.下列广义积分中发散的是 A 选项,即∫dx/(x^2+x+1)在区间 (-∞。

+∞) 内发散。

5.若 f(x) 与 g(x) 在 (-∞。

+∞) 内可导,且 f(x) < g(x),则必有 B 选项成立,即 f'(x) < g'(x)。

三、计算题(每小题7分,共56分)1.lim x^2(e^(2x)-e^(-x))/((1-cosx)sinx)lim x^2(e^(2x)-e^(-x))/((1-cosx)/x)*x*cosxlim x(e^(2x)-e^(-x))/(sinx/x)*cosxlim (2e^(2x)+e^(-x))/(cosx/x)应用洛必达法则)2.lim {arcsin(x+1) + arcsin(x-1) - 2arcsin(x)}/xlim {arcsin[(x+1)/√(1+(x+1)^2)] + arcsin[(x-1)/√(1+(x-1)^2)] - 2arcsin(x)/√(1+x^2)}lim {arcsin[(x+1)/√(1+(x+1)^2)] - arcsin(x/√(1+x^2)) + arcsin[(x-1)/√(1+(x-1)^2)] - arcsin(x/√(1+x^2))}lim {arcsin[(x+1)/√(1+(x+1)^2)] - arcsin(x/√(1+(x+1)^2)) + arcsin[(x-1)/√(1+(x-1)^2)] - arcsin(x/√(1+(x-1)^2))}lim {arcsin[(x+1)/√(1+(x+1)^2)] - arcsin[(x-1)/√(1+(x-1)^2)]} π/2 (应用洛必达法则)3.y = y(x) 由 x + y - 3 = 0 确定,即 y = 3 - x,因此 dy/dx = -1.4.f(x) = arctan(2x-9) - arctan(x-3) 的导数为 f'(x) = 1/[(2x-9)^2+1] - 1/[(x-3)^2+1],因此 f'(x)。
