This incantation worked for me:

#+name: foo
#+begin_src emacs-lisp :exports both :results drawer
  "Pseudo-function returning a LaTeX pseudo-result."
  "\\[\\displaystyle{\\sin\\left(\\frac{a}{b}\\right)}\\]"
#+end_src

#+RESULTS: foo
:results:
\[\displaystyle{\sin\left(\frac{a}{b}\right)}\]
:end:

the key is the drawer I think.
