## Homework Statement

V = the set of all symetrical nXn matrices, A=(ajk) such that ajk=akj

for all j,k=1,...,n

Determine the base and dimensions for V

## The Attempt at a Solution

I set my matrix up as

[a11 a12]

[a21 a22]

So a21 and a12 are equal to each other? I assume the others are 0. How can I use any axx in a linear combination?
