x＋cos(x＋y)＝0,求dy／dx,

x＋cos(x＋y)＝0,求dy／dx, ysinx-cos(x+y)=0,求 dy/dx 对于x=cos(y/x),求dy/dx. y= (cos x)^x,求dy/dx ysinX=cos(X—y)求导数dy/dX 若y=cos²x,求导数dy/dx dy/dx＝x/y＋y/x的通解 dy/dx=1-cos(y-x) ysinx+cos(x-y)=0,求dy/dx|(x=π/2) 求微分方程y－dy／dx=1＋x×dy／dx的通解 已知ysinx-cos(x+y)=0,求在点(0,π)的dy/dx值 e∧(x+y)+cos(xy)=0,求dy/dx, e^(-y^2)+cos(x^2)=0 求dy/dx是隐函数求导问题 求微分方程Y＊dx＋（x+y*y)dy=0 (x+y)dy+(x-y)dx=0求通解 ysin3x-cos(y-x)=5 y=f(x) 求dy/dx d{cos(x-y)=sin(x-y)(dx-dy)这里dx-dy是什么意思呢? 设y=y(x)由方程cos(x+y)+y=1,求dy/dx我做到-sin(x+y)*(x+y)'+y'=0
