User:Pfafrich/Blahtex \dot bugs

User:Pfafrich/Blahtex en.wikipedia fixup

This page is part a set of pages devoted to fixing latex bugs in the english wikipedia so that they will be compatable with the Blahtex MathML project.

Below are pages which contain combination of \dot, \hat etc. inside a math tag. Each occurence \dot\hat x should be replaced by \dot{\hat x} and when fixed the pages should be moved to the done section. Feel free to fix as necessary.

The combinations tested here are two consecutive symbols in: \ddot \dot \hat \bar \vec \overrightarrow\ \overleftarrow \widehat \overline \underline \underrightarrow \underleftarrow \overbrace \underbrace.
