$\overrightarrow{A}=3\text{\hat{i}}+4\text{\hat{j}}+5\text{\hat{k}}$

the above latex code is not working using JSMATH. If I remove \text its working.
Kindly let me know how to make \text to work in JSMATH.

• Your expression is not valid LaTeX code. The

\hat


macro is a math-mode macro, not a text-mode one, and so you can't use

\hat


inside

\text


(except by doing something like

\text{$\hat{i}$}


).  Also, jsMath doesn't process macros inside text-mode material (other than within embedded math like above), because jsMath only handle mathematical typesetting, not text typesetting.

If you are trying to get an upright i, j, and k rather than italics, try

3\hat{\rm i} + 4\hat{\rm j}+5\hat{\rm k}
