what does this mean (about vectors)?

Question

i have a problem on my hw about vectors and the addition of them with direction and such

it says add:
63mph, 45 degrees north of west << i get that
54 mph, due northeast<< wat the heck does due mean?

i need a degree like 45 or 90 or something but why do some problems use due? i have not a clue wat due means!

Answer 1

it means exactly northeast without any varriance in degree in compass speak.
go east is generally east
go due is exaclty east

Answer 2

sure. n linearly autonomous vectors right away span an area of measurement n. placed yet differently, (n+a million) vectors in an area of measurement n are absolute to be linearly based. which potential aX + by potential of + cZ = 0 for some a, b and c that are no longer all 0. And if X and Y are linearly autonomous, then c ought to no longer be 0 (or you will possibly have aX + by potential of = 0). so as which potential any Z could be written as a linear mix of X and Y, Z = (-a/c)X + (-b/c)Y. So given X and Y and any third vector Z, then Z is a linear mix of X and Y which potential the X and Y span the gap of all achieveable Z's.

Answer 3

Due means exactly.

Due northeast is halfway between due north and due east. The compass bearing of north (due north if you prefer) is 0° and the compass bearing of east (due east) is 90°. The compass bearing of northeast (due northeast) is 45°, which is midway between the two.

Answer 4

straight, directly or exactly
