I'm having trouble understanding bases outside of R^n; I've got a handle on those I think.
Here are some examples:
13. In C(-Pi,Pi), find the dimension of the subspace spanned by 1, cos(2x), and cos^2(x).
14. Find the dimension of the subspace of P3 spanned by x, x-1 , x^2+1, x^2-1
I really don't know how to begin either of these
Thanks for any input.
