Is is permissible to write an acceleration vector like they do in physics? So instead of the AP style <3t, t-4>, the vector could be written as (3t)i+(t-4)j?

Thanks

yes, you can... vectors can be written (at least, I know this forms) as:

sorry, I don't know why TeX isn't working in the last form :c - Feb 28th 2013, 06:10 AMbmnorvilRe: how to write an acceleration vector (for AP exam)
Thanks!

All my math students are in physics now so I was thinking it would be smart to keep the notation from physics consistent in math.

You can use \vec instead of \overlinearrow:

and array instead of pmatrix:

The <br\> thing happens when you put pieces of the array on separate lines.

Actually, it seems that pmatrix works:

In fact, I think I like that better than what I got before with array.
