求dy/dx+(1-2x/x^2)y=1的通解

y=f[(x-1)/(x+1)],f'(x)=arctanx^2,求dy/dx,dy 设y=√(x^2-1)求dy/dx x^2+xy+y^3=1,求dy/dx 求dy/dx-2y/x=1的通解 设y=sin2x/(1+x^2),求dy/dx, 设y=sin2x/(1+x^2),求dy/dx, 求dy/dx y=e^(2x+1) 求方程 dy/dx+x(y-x) +x^3(y-x)^2=1的通解~ dy/dx,y=(1+x+x^2)e^x dx/dy=1/y',求d^2x/dy^2 .为什么d^2x/dy^2不等于dx/dy求导?一个是二阶导数,一个是一阶导数 由方程y^2*sinx+e^y+2x=1,求dx/dy是dy/dx 打错了 dy/dx=(e^x+x)(1+y^2)通解 设y=（x/1-x)^x,求dy/dx x^y-y^x=2,求dy/dx 求dy/dx=(x-y+5)/(x+y-2) dy/dx=x(1+y^2)/y通解 (x^2)dy+（y^2)dx=dx-dy y=1(2x+1) 求dy/dx是y=e^(2x+1)
