sin(xy)+y^2-e^2 求dx/dy

sin(xy)+y^2-e^2 求dx/dy xy-sin(πy^2)=0 求dy/dx xy+e的平方+y=2 ,求dy/dx x=sin(y/x)+e^2 求dy/dx y=3^sinx,求dy/dx Y=e^2x sin^3x求dy 求方程e^y=xy确定的隐函数y=y(X)导数（e^y e^x+e^y=sin(xy),求dy/dx.怎么求 设e^xy-xy^2=Siny,求dy/dx 由2xy+e∧x-e∧y=0求dy/dx 已知e^y+e^x-xy^2=0,求dy/dx 设sin（xy）-x^2y=0,求dy／dx,求导什么的都要疯了! 设y=y(x)由方程e^xy+sin(xy)=y确定,求dy/dx. e^(xy)-(x^2)+(y^2)=1,求dy/dx
