# 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

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 $$\displaystyle \lambda = 1 - \chi$$?

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

True or false?? x/x =1
