# stacked \widetilde and \dot

I need to typeset (from bottom up) math bold L with above-dot and widetilde (both centered horizontally above the L), i.e. approximate time-derivative of tensor-valued function.

(I would google more, but being one-handed those days makes it a bit more difficult.)

Isn't

\widetilde{\dot{\mathbf{L}}}


working?

Thanks, and thanks @Mico. I thought the two would not work together in a trivial manner and did not even try. – eudoxos Sep 28 '11 at 8:17

The amsmath package should be loaded in the preamble. Then the following code should do what you need;

$\widehat{\dot{\mathbf{L}}}$
