Do you mean W_0 (x) by W(x)?  y=xe^x   x=W(x)e^(W(x))   ln x=ln W(x)+W(x)  (1/x)=(1/(W(x)))(d/dx)W(x)+(d/dx)W(x)  (1/x)=((1+W(x))/(W(x)))∙((dW(x))/(d(x)))  (d/dx)W(x)=((W(x))/(x(1+W(x))))
DoyoumeanW0(x)byW(x)?y=xexx=W(x)eW(x)lnx=lnW(x)+W(x)1x=1W(x)ddxW(x)+ddxW(x)1x=1+W(x)W(x)dW(x)d(x)ddxW(x)=W(x)x(1+W(x))
