e∧x+y=xy,求dy/dx

e∧x+y=xy,求dy/dx xy=e^(x+y)求dy/dx 求dy/dx+y/x=e^(xy) 由2xy+e∧x-e∧y=0求dy/dx e∧(x+y)+cos(xy)=0,求dy/dx, 设xy-e^xy=e 求dy/dx是=-y/x吧？ 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 已知xy+e^y=e...求dx/dy|x=0 求e^x+xy=e所确定的隐函数y的导数dy/dx 已知e^y+e^x-xy^2=0,求dy/dx高等数学求导 已知xy-e^x+e^y=0,求dy/dx 若y(x)是方程e^y=xy所确定的函数,求dy/dx? xy+e的平方+y=2 ,求dy/dx e^xy+x+y=2求dy/dx |x=1 求dy/dx...什么公式都用不上求dy/dxy-e^(-xy)=x-e^(xy)挑战自己!
