Problems:
Vector Spaces
How to prove or counter with example the following statements:
(1) If two subspaces are orthogonal, then they are independent.
(2) If two subspaces are independent, then they are orthogonal.
I know that a vector v element of V is orthogonal to a subspace W element V if v is orthogonal to every w element W. Two subspaces W1 and W2 are said to be orthogonal subspaces if for every w1 element W1 and w2 element W2 the inner product satisfies (w1, w2)=0
I would appreciate if you could provide proving explanation on two of above statements.
