How does one produce the equations and text displayed on the banner of this website? Here is a screenshot of the banner to show you.

It maybe difficult to see, so I played with the brightness and contrast:

• Maxwell Electrostatics Equation for EMF Induction

• Euler's Identity for Complex Numbers

For which the LaTeX code is:

$\mathrm{e}^{x+\mathrm{i}y}=\mathrm{e}^x(\cos(y)+\mathrm{i}\sin(y))$


And produces:
