In the process of writing an article about something that happened to me in the distant past (just over 25 years ago), I needed to put equations into an article. Not very complicated stuff, mind you, just some quantum mechanics. I promise QM is much easier to look at than some other, more elementary stuff that is much more complicated to typeset.

I wondered what the best approach would be. The original equations were typeset in TeX and fairly easy to reproduce in that language. I could do that, generate an image, and use it in the article. But you know me, the enemy of the good enough and focus on things at hand. I started looking at all the different options there were for inline equation typesetting in HTML. And man, there were tons of options!

Long story short, I settled on AsciiMath. It’s a really wonderful package, as it not only allows you typeset the equations you want, but also allows you to do so in a very intuitive way, without all the weird syntax you need to use in the other systems.

For instance, the equation I needed to typeset looks like this:{inlmath}

Psi (vec x, t=0) = cos alpha u_1(vec x) + sin alpha u_2(vec x), 0<alpha<pi/2

The code for it is simply:

Psi (vec x, t=0) = cos alpha u_1(vec x) + sin alpha u_2(vec x), 0<alpha<pi/2
