Test for \(LaTeX\) equation

• MathJax Test：

  • This is \(LaTeX\), and \int_{-\infty}^{+\infty}e^{-x^2}\mathrm d x=\sqrt{\pi} is rendered as \(\int_{-\infty}^{+\infty}e^{-x^2}\mathrm d x=\sqrt{\pi}\).

• KaTeX Test：

  • This is $LaTeX$, and \int_{-\infty}^{+\infty}e^{-x^2}\mathrm d x=\sqrt{\pi} is rendered as $\int_{-\infty}^{+\infty}e^{-x^2}\mathrm d x=\sqrt{\pi}$.

$$
\int_{-\infty}^{+\infty}e^{-x^2}\mathrm d x=\sqrt{\pi}
