f(x)=e^x/(x-1)对x求导

f(x)=e^x/(x-1)对x求导 f(x)=e^x/x求导 f(x)=x*e^-x求导 求导：f(x)=(e^x+1)/e^x 对F(X)=x(e^kx)求导详细步骤 f(x)=[(1+x)/(1-x)]e^(-ax)求导 f(x)=x*e^1/(x-1)求导全过程 F(X)=e^-x求导 f(x) = e^4 x + e^-7 x 求导 f(x)=e^ax/x-1求导. f(e^x+x^e)求导 f(x)=(x^2)e^x求导 f(x)=x^2*e^(-x)求导怎么求? 怎样对函数f(x)=(x^2+ax+b)e^(3-x) 求导, 求导:f（x）=e f(x)=e^(xcosx)求导 对e^x求导 结果是? 求导 x^(e^x)
