QUESTION: 10

The dimension of the vector space of all symmetric matrices A = (a_{ij}) of order n x n (n __>__ 2) with real entries, a_{ii} = 0 and trace zero is

Solution:

The dimension of the space of *n*×*n* symmetric matrices with diagonal equal to zero is . Now, in your case the diagonal is not zero but the sum of its elements is zero, that means that you have *n*−1 elements which can vary. SO you get as expected.
