As said in Requested articles/Linear algebra:

"Searching for "dual basis" directs to the article Dual basis in a field extension which is not helpful for someone who is trying to grasp the idea of a dual basis."

So I've stopped it from redirecting...I can't write the article tho; someone else who knows about it will have to...Scholarus 00:41, 15 December 2006 (UTC)

[edit] Orthogonality?

To quote the main aritcle:

In linear algebra, a dual basis is a set of orthogonal vectors that span (i.e., they form a basis for) the dual space of a vector space.

Is the condition of orthogonality unecessary? Frigoris 20:36, 1 July 2007 (UTC)
