By the last axiom of the inner product, vv 0, thus the length of v is always a non-negative real number, and the length is 0 if and only if v is the zero vector. Let P be the space of real polynomials, we deﬁne an inner product (related to the measure α) of two polynomials p and q ∈ P as hp,qi = Z b a p(λ)q(λ)dα(λ) (3) The norm of p is deﬁned as kpk = Z b a p(λ)2 dα(λ) 1 2 (4) We will consider also discrete inner products as hp,qi = Xm j=1 p(t. The inner product is an example of a bilinear form, and it gives the vector space a geometric structure by allowing for the definition of length and angles.
