dy/dx=?,if y=[3^√x+1]^4Y等于（x+1开3次方）^4,求dy/dx=?, if y=6x+1 then dy/dx=? 解方程 x(dy/dx)^3=(1+dy/dx) dy/dx=1+1/(x-y) dy/dx=1-cos(y-x) dy/dx=x(1-y) dy/dx = 1/x-y dy/dx=x+y 反函数的二阶导数疑问设dy/dx=y',则dx/dy=1/y',应视为y的函数则d2x/dy2=d(dx/dy)/dy（定义）=d(1/(dy/dx)) / dy=d(1/(dy/dx))/dx * dx/dy（复合函数求导,x是中间变量）=-y''/(y')^2 * (1/y')=-y''/(y')^3d(1/(dy/dx))/dx * dx/dy 设y=√(x^2-1)求dy/dx x^2+xy+y^3=1,求dy/dx dy/dx=3x+2y+1解微分方程 y=Insin(3x-1),求dx分之dy 微分方程(x+y)(dx-dy)=dx+dy的通解 (x^2)dy+（y^2)dx=dx-dy 求函数的导数dy/dx,和微分dy:y=x√1-x dy/dx=2y/x+3x/2y （-2x-y+9)dy=(-y+x+3)dx
