Question

Help check work with Writing a Vector as the Sum of Two Vector Components

Answer 1

Write v as the sum of two vector components if v = -5i + 6j and w = 3i + 4j

Answer 2

(-5*3)+(6*4)
-15+24
9

Answer 3

\[\frac{ 9 }{ \sqrt(6)^2+(4)^2 }=\frac{ 9 }{ 25 }(3,4)\]

Answer 4

v1= (27/25,36/25)

Answer 5

v2=v-v1= -5i + 6 - (27/25,36/25)

Answer 6

v2=(-152/25, 114,25)


v= (27/25i + 36/25j)+(-152/25i +114,25j)

Answer 7

too many problems, why did you multiply in the first

Answer 8

hm?

Answer 9

What do you mean

Answer 10

@zepdrix

Answer 11

hmm i don't understand the question 0_o

Answer 12

as the sum of two unit vectors or something?
what does this have to do with w?

Answer 13

Well to Write v as the sum of two vector components. V1= the projection from v to w. V2 = v-v1

Answer 14

Thats why the w is needed :p

Answer 15

vector projection? :o
mmm lil rusty.. thinking

Answer 16

bah i dunno >.<
