Question

If vector v lies in the second quadrant, makes an angle of 3pi/4 with the positive x axis and v = 6, find v in the component form

Answer 1

|v| = 6 perhaps?

Answer 2

pi/4 is 45 degrees

Answer 3

6 = sqrt(2)
s = 1

s = sqrt(2)/6 is the ratio of the side to hypotenuse then right?

Answer 4

s = 6/sqrt(2) :) had my ups and downs corssed

Answer 5

sorry hang on....it's 3pi/4

Answer 6

its still a 45; only the i part is - and the j part is +

Answer 7

ALRIGH....lemme solve real quick...will u verify it for me?

Answer 8

sure, if i can remember what it is im doing ;)

Answer 9

okay...so i get < -6/sqrt(2), 6/sqrt(2) >

Answer 10

good, and that can be simplified; to <-3sqrt(2),3sqrt(2)> right?

Answer 11

awesomeness...thx so much
