sin(xy)=x+e^y.y'=?

sin(x+y)+e^xy=4x,y'= sin(xy)=x+e^y.y'=? Sin(xy)=x+e^y求y'= sin（x+y）+e^xy=4 求y' 求函数导数e^x-e^y=sin(xy) Z=x*sin xy+e^x+y或设y=(x)是由方程xy+sin x+sin y=1确定,求y” y=y(x)由方程 [e^(x+y)]+sin(xy)=1确定,求y'(x)及y'(0) sin(x+y)+e^xy=4x,求y'=? 设y=y(x)由方程e^xy+sin(xy)=y确定,求dy/dx. 设隐函数y=y(x)由方程x^y-e^y=sin(xy)所确定,求dy 高数齐次方程问题xy'sin(y/x)+x=ysin(y/x)Cx=e^cos(y/x) sin（x+y)+e的xy=4求y的导数 sin(xy)=x+y,求dy sin(x*x+y)=xy 求y'x e^x+e^y=sin(xy),求dy/dx.怎么求 求隐函数的导数：sin y+e^x-xy^2=e 设y=y(x)是由方程e^x-e^y=sin(xy)所确定,求y',y'｜x=0 e^(xy)+sin(x+y)+1=0 隐函数求导e^(xy)+sin(x+y)+1=0 隐函数求导
