Here are some math examples. If you do not see math formulas, please ask for support.

Tall parentheses and fractions

$2=\left(\frac{(3-x)\times 2}{3-x}\right)$

Integrals

$\underset{a}{\overset{x}{\int }}\underset{a}{\overset{s}{\int }}f(y)dyds=\underset{a}{\overset{x}{\int }}f(y)(x-y)dy$

Integral equation

${\varphi }_n(\kappa )=\frac{1}{4{\pi }^2{\kappa }^2}\underset{0}{\overset{\mathrm{\infty }}{\int }}\frac{\sin (\kappa R)}{\kappa R}\frac{\partial }{\partial R}\left[R^2\frac{\partial D_n(R)}{\partial R}\right]dR$
