MathJax Example

• Quadratic Formula

\[ \begin{align} x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\label{eq:E} \end{align} \]

• State-Space equation

\[ \begin{align} \begin{bmatrix} \dot{x}_1 \\ \dot{x}_2 \end{bmatrix} &= \begin{bmatrix}0 & 1 \\ 0 & 0\end{bmatrix} \begin{bmatrix}x_1 \\ x_2\end{bmatrix} + \begin{bmatrix}0 \\ 1\end{bmatrix}u \label{eq:H} \end{align} \]

You can also type inline equations as \(A x = b\). Referencing equations is done as Eqs. \(\eqref{eq:E}\) and \(\eqref{eq:H}\).
