Matrix notation for vectors

[shinny]

Does anyone know if matrix notation for vectors is widely accepted by examiners given that it's not strictly part of the course? I've been told to use it since its much faster and easier to see whats actually going on (with the added bonus of not losing marks for forgetting to put the squiggly line under every bloody i and j <_<), but I'm reluctant to use it if I might lose marks for it. (I mean like, instead of xi+yj, I write )

might be safer just to stick with the i-j-k notation, as that is the form that they will give vectors to you in.

Yeh, I always write it in i-j-k for my final answer since it'll always be given in that form, but just to make it neater in the working out, do you think they'll mind if I use matrix?

Dr. G said yes and prefers to do it that way in class (matrix).
So yes.

But, if you're forgetful about converting it back to ijk form, don't do it.

Otherwise enjoy.

i've heard from MAV that they do not penalize you for proper notations, i.e. column vectors such as are allowed. So too are

however, I'd rather not risk it =P

Wow, I've never seen used for vectors before. Surely it's more common to just use ?

i'll stick to my confusing squiggly lines thank you.
