The following surrounds the fraction a/b with parentheses that are sized appropriately. You can also use brackets and braces.
$\qty( \frac{a}{b} )$
$\qty[ \frac{1-x^2}{2x} ]$
$\qty[ \frac{1-x^2}{2x} ]$
For the measure in an integral, use \dd{x}, which sets the d in roman font and adjust spacing before it according to context. Use \dv{x} for d/dx, \dv{f}{x} for $\df/dx$, and \dv*{f}{x} for an inline version. Similar expressions for partial derivatives use \pdv.
\begin{equation}
\Gamma[n+1) = \int_{0}^{\infty} x^n e^{-x} \dd{x}
\label{eq:gamma}
\end{equation}
For vectors, you can use \vb{F} or \vb*{\sigma) for vectors set in boldface, \va{F} or \va*{\theta} for an arrow, and \vu{a} or \vu*{\theta} for unit vectors. There is also full support for Dirac bra-ket notation.
