Question
The linear combination should be rewritten as W
B
Since the coordinate mapping x→[x] is a(n)
B
maps to [w], namely the combination
above.
=
w which
which can be seen in the rewritten expression
transformation, there exists
This shows the "if" portion of the proof. The "only if" portion can be constructed by applying the same logic in
reverse.
