sin(xy)+ln(y-x)=x,求y`

sin(xy)+ln(y-x)=x,求y` sin(xy)+ln(y-x)=x,求y sin(xy)=ln(x+y)/y+1,求y'(0)要过程 sin(xy)-ln(x+1)/y=1 /y在ln内 求y的二次导数 已知sin(xy)=ln((x+1)/y)+1,求y'(0). 求解微分方程xy'ln(x)sin(y)+cos(y)(1-x*cos(y))=0 已知sin(xy)-ln((x+1)/y)=1 求dy/dx 求方程xy''=y'ln(y'/x)的通解 e^y+ln(xy)-e^(-x)=0,求y' xy=y'ln(y'/x) sin(x*x+y)=xy 求y'x y/x=ln(xy) 求dy/dx(xy-y^2)/(xy+x^2) sin(xy)=x+y,求dy y/x=ln(xy) 求详 dy/dx z=ln sin(xy) 则 z'y=x cot(xy).判断这题对错. 求导数 y=sin ln(x²) 求y=ln(sin(1/x)^2)的导数 求定义域 y=ln（sinπ/x)
