求函数y=x/1-x^2的微分(带步骤)
求函数y=x/1-x^2的微分(带步骤)

求函数y=x/1-x^2的微分(带步骤)
y=x/(1-x^2)
y'=[(x)'(1-x^2)-x*(1-x^2)']/(1-x^2)^2
=[(1-x^2)-x*(-2x)]/(1-x^2)^2
=(1+x^2)/(1-x^2)^2

dy
=y'dx
=(1+x^2)/(1-x^2)^2dx

y=x/(1-x²)
y'=[x'(1-x²)-x(1-x²)']/(1-x²)²
=[(1-x²)+2x²]/(1-x²)²

dy=[1*(1-x^2)-x*(-2x)]/[(1-x^2)^2]
=(1+x^2)/(1-x^2)^2 dx
