\[
\int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi}
\]
\[
\nabla \cdot \mathbf{E} = \frac{\rho}{\varepsilon_0}
\]
Matrix
\[
\mathbf{A} = \begin{pmatrix} a & b \\ c & d \end{pmatrix}, \quad \det(\mathbf{A}) = ad - bc
\]
Summation and Limits
\[
\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}
\]
\[
\lim_{x \to 0} \frac{\sin x}{x} = 1
