vectors

[tiffany88]

for those of you who keep emphasizing vectors being in the math section, what did you mean by that? basically just adding vectors and such or is it a lot harder than that? also, how should i prepare for the writing portion of the test? is it usually just over current events? thanks in advance

Yes, there was an addition or subtraction problem, but then there was another one that confused me. I totally forgot what it was, but it definitely wasn't a basic proof that I remember. Probably a research question honestly, but who knows. Just know the basics, addition, subtraction, division, multiplication, and magnitude.

Magnitude of v = 5i + 5j <5,5> would be:

||v|| = sqrt(5^2 + 5^2) = 5*sqrt(2)
