Limits are placed on integrals using superscripts and subscripts: \[ \int_0^1 \frac{dx}{e^x} = \frac{e-1}{e} \] Lower case Greek letters are written as $\omega$ $\delta$ etc. while upper case Greek letters are written as $\Omega$ $\Delta$. Mathematical operators are prefixed with a backslash as $\sin(\beta)$, $\cos(\alpha)$, $\log(x)$ etc. \end{document}
