sin(x+y)+e^xy=4x,求y'=?

sin（x+y）+e^xy=4 求y' Sin(xy)=x+e^y求y'= sin(x+y)+e^xy=4x,y'= 求函数导数e^x-e^y=sin(xy) sin(x+y)+e^xy=4x,求y'=? sin（x+y)+e的xy=4求y的导数 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*x+y)=xy 求y'x sin(xy)=x+e^y.y'=? sin(xy)=x+y,求dy 设隐函数y=y(x)由方程x^y-e^y=sin(xy)所确定,求dy sin(xy)+ln(y-x)=x,求y` sin(xy)+ln(y-x)=x,求y 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. sin(xy)=x 求dx/dysec(xy)-y ]/x 还是 x/[sec(xy)-y] 设y=y(x)是由方程e^x-e^y=sin(xy)所确定,求y',y'｜x=0
