Please suggest me a way to put tilde over a symbol phi. I can easily put it over a letter but coming to the case of symbols, it is giving problems. Thanks in advance.

    What about $\tilde{\phi}$? Aug 9, 2012 at 6:39

    More generally: accents in math mode use different commands to accents in text mode. Aug 9, 2012 at 9:07

Does \widetilde{\phi} work for you?

If you enter this in http://www.codecogs.com/latex/eqneditor.php, it produces a nice Phi with Tilde.

    In my case, I wanted a tilde over an M_{A}. I had to use \widetilde{M}_{A} so that the tilde is the full width of the M without extending over the subscript as well.
