## Main Question or Discussion Point

Hi there,

During a recent tutorial, I asked my tutor about the notation he uses for vectors - he draws the little half arrow above them and I was curious whether that was significant, as opposed to just underlining vectors. He said it was a mathematical technicality and suggested I look up "forms versus vectors" on Google. However, I haven't been able to find anything conclusive. Could anyone explain the difference between forms and vectors, and the difference in notation?

Thanks!
