Re: [NTG-context] Package esvect and Context

2016-06-06 Thread josephcanedo
Hi Fabrice,


Have you tried \vec command ?


\startformula


\vec{AB} = \vec{AC} + \vec{CB}


\stopformula


Best regards


Joseph

Hello everyone,
When I used LaTeX, I was writing the vectors with esvect package.
Is there an equivalent with Context ?
