Math (KaTeX)

Inline math: the quadratic equation $ax^2 + bx + c = 0$ has solutions $x_1$ and $x_2$.

Display math:

$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$

Currency like $5 and $10 stays as plain text.

LaTex Examples

Inline formulas：$E = mc^2$

Block-level formulas： $$ \int_{-\infty}^{\infty} e^{-x^2} , dx = \sqrt{\pi} $$

More complex examples： $$ \begin{cases} \nabla \cdot \mathbf{E} = \frac{\rho}{\varepsilon_0} \[2ex] \nabla \cdot \mathbf{B} = 0 \[2ex] \nabla \times \mathbf{E} = -\frac{\partial \mathbf{B}}{\partial t} \[2ex] \nabla \times \mathbf{B} = \mu_0 \mathbf{J} + \mu_0 \varepsilon_0 \frac{\partial \mathbf{E}}{\partial t} \end{cases} $$
