definition

This page should give a definition of a basis function first, bolding the key word. Fresheneesz 05:45, 23 March 2006 (UTC)[reply]

Square integrable

There is a problem about sine and cosine not being square integrable but being used as basis vectors for a space of vectors that are square integrable. If I tried to fix it, the language might not be right. David R. Ingham 01:49, 9 September 2006 (UTC)[reply]

a comment

this page is sloppily written and redundant. it omits essential mathematical details and claims to be mathematics. the topic it purports to discuss is covered in much better fashion in Hamel basis, Hilbert space, and probably other pages. one might wanna consider replacing the math categories by physics ones. (IMHO, it certainly doesn't belong in the functional analysis category) Mct mht 05:53, 9 September 2006 (UTC)[reply]
