what does this inversed triangle stand for?

It is called nabla, which is the name of the symbol but not it's meaning.
In Calculus, you can find it (alone) as an operator meaning "denotes the vector of partial derivatives":
$$\nabla = \left(\frac{\partial}{\partial x},\ \frac{\partial}{\partial y},\ \frac{\partial}{\partial z}\right)$$
If you are in three dimensions.
In your case, the $x$ subscripts indicates the only $x$ component of the gradient:
$$\nabla_x = \frac{\partial}{\partial x}$$
