dy/dx=(x+y)/(x-y),求y=f(x).
dy/dx=(x+y)/(x-y),求y=f(x).
dy/dx=(x+y)/(x-y),求y=f(x).
dy/dx=(x+y)/(x-y),dy/dx=(1+y/x)/(1-y/x)
u=y/x,dy/dx=u+xdu/dx
(1+u)/(1-u)=u+xdu/dx
dx/x=(1-u)du/(1+u^2)
ln|x|=arctanu-(1/2)ln|1+u^2|+C
(1/2)ln|x^2+y^2|-arctan(y/x)=C
y=tan(x+y),求dy/dx
dy/dx=(x+y)/(x-y),求y=f(x).
解方程(x+y)dy/dx=y-x
(cosy)^x=(sinx)^y求dy/dx
y = sin²(x²)求 dy / dx
(dy/dx)-y=x求微分方程
y=(sinx)^x 求DY/DX
y=x+lnx,求dx/dy
求dy/dx= - x/y
dy/dx=x+y
5.求齐次方程dy/dx=y/(x-y)
(x+y)dy+(x-y)dx=0求通解
设 x/y=ln(y/x) ,求 dy/dx
dy/dx=(x+y)/(x-y)求通解
x^y-y^x=2,求dy/dx
求dy/dx=(x-y+5)/(x+y-2)
求微分方程 x*dy/dx=y*ln(y/x) .
dx/dy 是相当于 y=f(x)求一阶导数吗dx/dy是指y对x求导还是什么dy/dx呢.
