Maxwell's equations

How to do this? Just download Amaya and experiment its math feature. You can also read the online manual page about math editing.

Here is how it looks in your browser:

$\nabla ·E=\frac{\rho }{{\epsilon }_0}\text{ ; }\nabla \times E=-\frac{\partial B}{\partial t}\text{ ; }{c}^2\nabla \times B=\frac{\partial E}{\partial t}+\frac{j}{{\epsilon }_0}\text{ ; }\nabla ·B=0$

Here is the source code representing the beginning of the above expression, but you don't need to learn that language: a few simple commands in Amaya allow you to build complex expressions in a few seconds.
