# Thread: Vectors: OAB is triangle, vector OA = a, vector OB = b

1. ## Vectors: OAB is triangle, vector OA = a, vector OB = b

I was doing a question on vectors and I somehow managed to make the vector a equal to vector b. This shouldn't be possible since the have different directions so even if the had the same magnitude they wouldn't have the same vector. Have I done something wrong or can someone explain. My hand writing is bad but it is fairly easy to read [/CODE][/CODE]

2. 1) What is it that you are asked to demonstrate or prove?

2) Where did you use the given ratio or the given parallel parts?

3) Can it be that $\lambda = 1 - \chi$?

Might you be dividing by 0? Is 1/3 + 2/3 = 1??

True or false?? x/x =1
