Question

Please help! This problem I'm having troubles with :/ Please click on attached

Answer 1

isn't there like a formula for this?

Answer 2

well to find the scalar you have to find the vector projection first....
do you know how?

Answer 3

:/ No

Answer 4

projection u onto v = (dot product of u and v over the magnitude of v squared)* vector v

Answer 5

after you find out the product you would then just find the magnitude of it to get your scalar projection

Answer 6

Oh o.k. Is it -1?

Answer 7

Oh wait...

Answer 8

oh w8 i kind of explained it wrong...

Answer 9

proj_b (a) = a•b/|b|

Answer 10

so ya its -1
