Adding Equations to Your Blog | Modeling and Experimental Tools with Prof. Magnes

You can type LaTeX code directly onto WordPress. For example, Maxwell’s equations can be displayed in all their glory:

(1) $\begin{equation*} \nabla \cdot \vec{E} = \frac{\rho}{\epsilon_0} \end{equation*}$

(2) $\begin{equation*} \nabla \cdot \vec{B} &=& 0 \end{equation*}$

(3) $\begin{equation*} \nabla \times \vec{E} &=& - \frac{\partial B}{\partial t} \end{equation*}$

(4) $\begin{equation*} \nabla \times \vec{B} &=& \mu_{0}\vec{J} + \mu_{0}\epsilon_{0}\frac{\partial E}{\partial t} \end{equation*}$
