微积分基础题 求大神解题过程!!急!!!
下面是用计算机计算的结果,整理了一份文档可以下载:
3
limit((2*x^2-32)/(x+4),x,-4)
ans =
-16
4
limit((1-3/x)^(2*x),x,inf)
ans =
exp(-6)
5
limit((exp(x)+cos(x)-2)/(3*x),x,0)
ans =
1/3
6
diff(4*(sqrt(x^3) )-5*sin(x)+2*log(x)-exp(4) )
ans =
(6*x^2)/(x^3)^(1/2) - 5*cos(x) + 2/x
7
diff(3*cos(x)*exp(2*x))
ans =
6*exp(2*x)*cos(x) - 3*exp(2*x)*sin(x)
8
diff(log(1-3*x)^2)
ans =
(6*log(1 - 3*x))/(3*x - 1)
9
diff(2/x^2+sqrt(x-2))
ans =
1/(2*(x - 2)^(1/2)) - 4/x^3
10
diff(3^(acos(x)))
ans =
-(3^acos(x)*log(3))/(1 - x^2)^(1/2)
11

想逆天不是?
会做多少就多少吧,只求过程详细
