a)
Consider the following definition of inner product:
Definition of Inner Product Space
Suppose u, v, and w are all vectors in a vector space Vand c is any scalar. An inner product on
the vector space V is a function that associates with each pair of vectors in V, say u and v, a real
number denoted by (u, v) that satisfies the following axioms:
1. (u, v) = (v, u)
2. (u + v, w) = (u, w) + (v, w)
3. (cu, v) = c{u, v)
4. (u, u) > 0 and (u, u) = 0 if and only if u = 0
Suppose that u, v, and w are vectors in an inner product space such that
(u, v) = 1,
(u, w) = 5,
(v, w) = 0,
||u|| = 1,
||v|| = v3,
||w|| = 2.
Show that u +v = w.
