Given
Determine a vector in (which are NOT scalars of thats in the Span{ } but is NOT in Span{ }. Justify your answer.
Attempt:
So I think what they want me to do is find values a, b, c for:
that make it consistent but what make
inconsistent.
ok, you did well setting up the matrices.
note that the solution to the first is:
(you should probably check this, i always mess up the arithmetic somewhere because i try to do it in my head )
the solution to the second is:
hmm, something looks familiar here.
note that the latter matrix is inconsistent if . so choose a,b, and c that work for the first solution but make and you can find your vector.
