I don't know why this one is giving me such a hard time but it is:
Find a basis for the set of vectors in R^3 in the plane x + 2y + z = 0
Ok, I think I get it.
So you're saying that as long as I pick two vectors in R3 that are linearly independent and satisfy the equation, that I am good?
Thank god for this site! Especially when you are taking a class that normally covers 4 months in four weeks!
