MathJax

jemdoc-rs uses MathJax 4 for math rendering. MathJax is always included unless the noeqs directive is set.

Inline Math

The energy–mass equivalence \(E = mc^2\) and Euler's identity \(e^{i\pi} + 1 = 0\) are inline equations.

\[ \nabla \times \mathbf{E} = -\frac{\partial\mathbf{B}}{\partial t} \]

Aligned Equations

Use LaTeX's aligned environment for multi-line equations without numbering:

\[ \begin{aligned} \nabla \cdot \mathbf{D} &= \rho_f\\ \nabla \cdot \mathbf{B} &= 0\\ \nabla \times \mathbf{E} &= -\frac{\partial\mathbf{B}}{\partial t}\\ \nabla \times \mathbf{H} &= \mathbf{J}_f + \frac{\partial\mathbf{D}}{\partial t} \end{aligned} \]

Numbered Equations

Use LaTeX's equation environment to number a block as a single equation:

\[ \begin{equation} \begin{aligned} \nabla \cdot \mathbf{D} &= \rho_f\\ \nabla \cdot \mathbf{B} &= 0\\ \nabla \times \mathbf{E} &= -\frac{\partial\mathbf{B}}{\partial t}\\ \nabla \times \mathbf{H} &= \mathbf{J}_f + \frac{\partial\mathbf{D}}{\partial t} \end{aligned} \end{equation} \]

Use align to number each equation individually:

\[ \begin{align} \nabla \cdot \mathbf{D} &= \rho_f\label{eq:D}\\ \nabla \cdot \mathbf{B} &= 0\label{eq:B}\\ \nabla \times \mathbf{E} &= -\frac{\partial\mathbf{B}}{\partial t}\label{eq:E}\\ \nabla \times \mathbf{H} &= \mathbf{J}_f + \frac{\partial\mathbf{D}}{\partial t}\label{eq:H} \end{align} \]
