y=Inu(x)/Inx,其中x>0且x≠1,u(x)可导,求dy/dx

已知y=logx u(x),其中x>0且x不等于1,u(x)可导,求dy/dx 设y=y(x)由方程xe^f(y)=e^y确定,f(u)可导且f′≠1,求dy/dx 设y=f(x-y)其中f可导且f'≠1则dy/dx=? 设f(x)可导,且f'(0=1,又y=f(x^2+sin^2x)+f(arctanx),求dy/dx /x=0 设f(x)可导,且y=f(x²)+f[f(x)],求dy/dx 设f(x)为可导函数,求dy/dx:y=f(arcsin(1/x)) 设y=（x/1-x)^x,求dy/dx f(x)可导,且y=f(e^-x),则dy/dx= (x+y)dy+(x-y)dx=0求通解 1、设y=x+Inx,则dx/dy=() A、（x+1）/x B、(y+1)/y C、x/(x+1) D、y/(y+1) 设f(x)可导,求dy/dx y=sin f(x²) 设f x 为可导函数,y=f^2(x+arctanx),求dy/dx
