Help! does anybody out there know how to put a superscript on the LEFT side of an expression, such as: A dv ---- dt The reason for this is so that I can write equations with components that are in different reference frames. It would be nice to have this as a feature similar to v^{A}, but I'll take whatever I can get. I have looked through the LaTeX book and cannot find any clues. Thanks, Ian Searle

Just do it. \frac{^A dv}{dt} or ^A\frac{dv}{dt} if you mean the latter. For readability these can be turned into \frac{{}^A dv}{dt} or {}^A\frac{dv}{dt} but Knuth says it doesn't matter, either form works. See p. 129 in the TeXbook. There is no point in looking in the LaTeX book for things like this. Lamport obviously meant that you look in the TeXbook for what he doesn't cover.

Usually if you just want a left superscript on a character, $^{whatever}$ will do. Roscoe -- ######################################################################## # Jenwei R.
