高等数学xy=e^(x+y) 求dy、xy

xy=e^(x+y),求dx/dy e∧x+y=xy,求dy/dx 求dy/dx+y/x=e^(xy) 求导：xy=x-e^xy,求dy/dx y=y(x)的导数dy/dx 求 XY=e的X+Y次方? xy-e^x+e^y=0,求dy/dx|x=0? e^x+e^y=sin(xy),求dy/dx.怎么求 设y=y(x)由方程e^xy+sin(xy)=y确定,求dy/dx. 设y=y(x)由方程e^xy+cos(xy)=y确定,求dy(0). 设 e^(x+y) - xy = 1,求 dy/dx \ x=0 y=0 设e^(x+y)+cos(xy)=0确定y是x的函数求dy 已知xy+e^y=e...求dx/dy|x=0
