  Hi, Sorry if this has been asked before. How do I write a LaTeX equation involving <? What I’ve been doing is writing two equations (one before, one after) with html code < in between. Is there a direct way?

  Thanks!
  AndrEs

  Been so long since I did anything in Tex….

  The less than symbol? Should be just that:

  <

  At least that’s what this guide says.

  Looking at the demo shows that as well.

  Hi drmike. Thanks, that’s what I hoped but yesterday it didn’t work. Maybe it was a temporary glitch.

  It should work. You are putting the ‘$latex’ bit at teh beginning and the ‘$’ mark at the end, right?

  Demo

  I used this out of the faq demo:

  $latex ihbarfrac{partial}{partial t}left|Psi(t)right>=Hleft|Psi(t)right>$

  Do note that I’m using the regular text editor, not the fancy editor with the icons along the top. You can switch between them at Dashboard -> users -> Your profile -> Uncheck the box at teh top of that page.

  If you use the HTML entity for < (&lt;), wordpress will convert it back into an actual less-than symbol for LaTeX processing. It’s pretty ugly, imo, but it seems to work.
