Spanning: If p1,p2,...,pm span Pn, what is relation between

[jacko]

* If p1,p2,……pm span Pn, write down a mathematical relationship between m and n.

I know that Pn means the space of all polynomials of degree at most n, and this is an (n+1) dimension space, but im not sure what kind of mathematical relationship the question is looking for :s

Any help is greatly appreciated!!

A spanning set has to contain at least as many elements as a basis. The question is just asking for a simple inequality to express that fact.
