Is this symbol equivalent to taking a partial derivative? On the Wikipedia page for the Leibniz Rule for Integration, it displays this formula:
$$
\frac{d}{dx}\int f(x,t)\,dt = \int\partial_xf(x,t)\,dt
$$
Is the symbol $\partial_x$ equivalent to $\frac{\partial}{\partial x}?$ If so, is this just a preference of convention? If I use this symbol, will people get confused?

$\partial_xf(\cdot)$ and $\frac\partial{\partial x}f(\cdot)$ denote completely the same thing, and nobody will be confused. The former way is just a more concise formulation.
