y=(x^2-2x+2)/(x-1)求导?谢谢!y=(x^2-2x+2)/(x-1)求导?谢谢!y=(x^2-2x+2)/(x-1)求导?谢谢!y=(x²-2x+2)/(x-1)=x-1+1

y=(x^2-2x+2)/(x-1)求导?谢谢!
y=(x^2-2x+2)/(x-1)求导?谢谢!

y=(x^2-2x+2)/(x-1)求导?谢谢!
y=(x²-2x+2)/(x-1)
=x-1+1/(x-1)
所以y'=1-1/(x-1)²

y=2^x+1/x求导 y=x/(1+x^2)求导求导 y=x/[(2x+1)^2]求导 y=x^2求导 y=(x+1)(x-1)(x-2)求导 y=x[arcsin (x/2)]求导 y=2x+8/x求导 y=3^-x*x^2,求导 y=2^x-cosx/x求导 y=x^(x^2)求导 y=x/(x^2+3)求导求导：y=1/(cosx)^2 对x求导函数求导,y=x^2+2/x如何求导? cos(xy^2)=x+2y求导 y=x^1/x求导 y=lnx/(x^2+1)求导 y=ln(2x^-1)求导 y=ln(1+x^2)求导 y=ln^2(1-x)求导
