隐函数求导\:\frac{dy}{dx},\:(x-y)^2=x+y-1 \frac{\partial}{\partial y\partial x}(\sin (x^2y^2)) \frac{\partial }{\partial x}(\sin (x^2y^2))

进行约分: f’(x)=lim dx->0 2x+dx 因为dx是一阶无穷小，所以f’(x)=2x 以上就是x^2导数的严格求导过程，我相信题主能看明白，谢谢

上式中d^2 实际上是 dd 的两次微分算符；而 dx^2 则是两个 dx 相乘。 这就是为什么不能用后两种表示，因为微分运算 d 和微变 d 需要区分开，避免产生歧义。

dx表示是变量x的微分。 比如我们说的y’=dy/dx，这里实际上对应的是函数y的微分dy与自变量x微分dx的 微商。即dy/dx， 变形有 dy=y' dx; dx^2 则表示 x²的微分，(x²)'dx =2xdx; ∫2x dx^2表示 2x与dx^2的乘积， 即∫2x*(2xdx) =∫4x²dx
