Vectors

[nicholasjgroo]

1. The problem statement, all variables and given/known data
the vectors a and b


2. Relevant equations
find a vector which is perpendicular to the plane containing vectors a and b


3. The attempt at a solution

do i find the vector product of a and b and then find something that's parallel to that or....?

[CompuChip]

Yes, that's a good one.

Hint: note that the vector v is parallel to the vector v.

[Seannation]

The vector product will give you a vector that is perpendicular to both a and b. This should be sufficient to answer the question, I don't think you need to find another which is parallel to this vector.
