Consider the set of vectors in the real vector space R3
1 0 1
3 1 p
3 -p -1
For what value(s) p is the set of vectors linearly independent?
Ok, so. I think I'm on the right path.
For A set of vectors to be Linearly independent, the determinent cannot = 0
So i found the Det of that matrix to be p^2 - 3p - 4 and got that p cannot equal 4, or -1. Because that would make the det = zero.
So is he answer all real numbers besides 4 and - 1?
