Question

What is the magnitude and direction of Vector GH if G(3, -2) and H(6, 4)?

magnitude: 6.71 units; direction 63.43°

magnitude: 6.71 units: direction: 26.57°

magnitude: 3.61 units; direction: 26.57°


magnitude: 3.61 units: direction: 63.43°

Answer 1

let two points be: P(a,b) Q(c,d)
vectors PQ direction is (c-a,d-b)
vectors PQ magnitude is:
\[\sqrt{(c-a)^{2}+(d-b)^{2}}\]

Answer 2

okay so the answer is the first one

Answer 3

to find direction in degrees use this:
\[degrees = arctg ((d-b)/(c-a))\]

Answer 4

but what do the letter stand for

Answer 5

let two points be: P(a,b) Q(c,d)

Answer 6

okay
