sin(xy)=x+y,求dy

设sin(x+y)=xy,求dy/dx. sin(xy)=x 求dx/dy sin (x^2+y^2)+e^x-xy^2=0求dy 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. y=x*sin(lnx) 求dy 设sin（xy）-x^2y=0,求dy／dx,求导什么的都要疯了! 设隐函数y=y(x)由方程x^y-e^y=sin(xy)所确定,求dy xy-sin(πy^2)=0 求dy/dx 设y=y(x)由方程x^2-sin(xy)=2y确定,求dy/dx （1）y-sin（Inx）求y （2）（e^x+y）-xy=0求dy 设函数y=f(x)由方程sin(xy)+e^(x+y)=0确定,求dy/dx
