Which of the following sets of polynomials form a basis for P2
(the space of polynomials of degree at most 2)? Explain. (a) {2 +
2x − x 2 , 1 + x, 3x} (b) {1 − x + 2x 2 , 2 + 4x} 1 (c) {3 + x + x
2 , −1 + x, 5 − x + x 2}
Let P2 be the vector space of all polynomials of
degree less than or equal to 2.
(i) Show that {x + 1, x2 + x, x − 1} is a basis for
P2.
(ii) Define a transformation L from P2 into
P2 by: L(f) = (xf)' . In other words,
L acts on the polynomial f(x) by first multiplying the function by
x, then differentiating. The result is another polynomial in
P2. Prove that L is a linear transformation....
Consider the vector space P2 of all polynomials of degree less
than or equal to 2 i.e. P = p(x) = ax + bx + c | a,b,c €.R
Determine whether each of the parts a) and b) defines a subspace in
P2 ? Explain your answer. a) ( 10 pts. ) p(0) + p(1) = 1 b) ( 10
pts.) p(1) = − p(−1)
Consider the vector space P2 := P2(F) and
its standard basis α = {1,x,x^2}.

Which of the following sets of information does an auditor
usually confirm on one form?

Show that the Legendre polynomials P1 and P2 are orthogonal by
explicit integration. Also show that when (P2)^ 2 is integrated
over the full range of integration, the result is 2 /(2l+1) , where
l is the order of the polynomial.
