Y=xloga(x^2 x-1) Y=log2((x-1)/(x 1)) 求導數,
Y=xloga(x^2 x-1) Y=log2((x-1)/(x 1))
求導數,網友廻答：
- 複郃求導：dy/dx=loga(x^2 x-1) (2x 1)*{1/[(x^2 x-1)*lna]}
y=2log((x-1)/(x 1))
dy/dx=4/(x I)^2*{1/[(x-1)/(x 1)*lna]}
網友廻答：
- 1:y'=x*[loga(x^2 x-1)]' loga(x^2 x-1) =x*(2x 1)/[lna*(-1 x x^2)] loga(x^2 x-1) =(2x^2 x)/[lna*(-1 x x^2)] loga(x^2 x-1)2:y'=(x 1)/[Ln2(x-1)]*[(x - 1)/(x 1)]' =(x 1)/[Ln2(x-1)]*[(x 1)-(x-1...
