$$\begin{pmatrix}a_{11} & a_{12} & a_{13}\ a_{21} & a_{22} & a_{23}\ a_{31} & a_{32} & a_{33}\end{pmatrix}$$

$$a^2+b^2=c^2$$

$$
i\hbar\frac{\partial}{\partial t}\psi=-\frac{\hbar^2}{2m}\nabla^2\psi+V\psi
$$

\begin{eqnarray*}
\nabla\cdot\vec{E}&=&\frac{\rho}{\epsilon_0}\\
\nabla\cdot\vec{B}&=&0\\
\nabla\times\vec{E}&=&-\frac{\partial B}{\partial t}\\
\nabla\times\vec{B}&=&\mu_0\left(\vec{J}+\epsilon_0\frac{\partial E}{\partial t}\right)\\
\end{eqnarray*}
