Question
Consider the space P₂ which is the vector space of polynomials of degree not greater than two. We define the inner product in P2 according to the formula
-Lpqdz.
Also, consider the following two vectors
(a)
Calculate the inner product (p, q)
(b)
Calculate the distance between vectors p and q.
(c)
Calculate the norm ||q||, of vector q.
(p, q)
(e)
For vectors p and q, calculate the inner product (p - q, p + 2q).
p = x² = 5x + 1, q= −2x²+x.
(d)
For vectors p and q, find the orthogonal projection of p on q (projp). Your answer must be a vector from P2, i.e. a polynomial of degree 2 or less.

Expert Solution
Step 1: Introduction of the given problem

open angle brackets p comma q close angle brackets equals integral subscript negative 1 end subscript superscript 1 p q d x
p equals x squared minus 5 x plus 1
q equals negative 2 x squared plus x

Note: According to the guidelines we are allowed to solve three subparts at a time. So please post rest of the subparts separately
