## Math test

$E=mc^2$
$e^{i\phi} = \cos\phi + i\sin\phi$
$전압 = 전류 \times 저항$
$償還までの合計利回り =\left(1+\frac{期間利率}{100}\right)^{期間}$
$\begin{bmatrix} a & b \\ c & d \end{bmatrix}$

### Lorenz equations

\begin{align} \dot{x} & = \sigma(y-x) \\ \dot{y} & = \rho x - y - xz \\ \dot{z} & = -\beta z + xy \end{align}

### Maxwell's equations in Gaussian unit

\begin{align} \nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\ \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\ \nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\ \nabla \cdot \vec{\mathbf{B}} & = 0 \end{align}
