1. If the vectors
and
are orthogonal with respect to the weighted inner
product
<

, what must be true about the weights
?
2. Do there exist scalars k and m such that the vectors p1 =
2+kx+6, p2 =
m+5x+3 and
p3 = 1 + 2x + 3 are mutually
orthogonal with respect to the standard inner product on P2?

Consider the following three vectors in
; v1 = (1, 7, −2), v2 = (4, 3, 5), v3 = (2, −11, 9):
i) Say whether v1, v2, v3 are linearly dependent or linearly
independent. (Justify)
ii) Say if v1, v2, v3 generate
. (justify)
iii) If it exists, determine the constants c1, c2, c3, such that
c1v1 + c2v2 + c3v3 = (0, −5, 13/5), or argue why it cannot be
written as a linear combination.

Let S ⊆
be the tetrahedron having vertices (0, 0, 0), (0, 1, 1), (1, 2,
3), and (−1, 0, 1).
Let f :

be the function defined by f(x, y, x) = x − 2y + 3z.
Using the change of variables theorem,
rewrite
as an integral over a 3-rectangle, then use Fubini’s theorem to
evaluate the integral.
