6. (15 pts) Consider an inner product on the vector space P2[-1, 1] of polynomials of degree 2 or less in the closed interval [-1, 1], defined as follows: (f, 9) = | f(t)g(t) dt, for all f, ge P2[-1, 1]. Apply the Gram-Schmidt process to the basis {3, t – 2,t2 + 1} to obtain an {x1, X2, X3} = %3D orthonormal basis.
Consider the inner product space V = P2(R) with (5,9) = { $(0)g(t) dt, and let T:VV be the linear operator defined by T(f) = x f'(x) +2f (x) +1. (i) Compute T*(1 + x + x2). (ii) Determine whether or not there is an orthonormal basis of eigenvectors ß for which [T]k is diagonal. If such a basis exists, find one.
11. In an introductory calculus course, you may have seen of the form approximation formulas for integrals f(t)dt wf(a,), 2 where the a, are equally spaced points on the interval (a,b) and the u, are certain "weights (giving Riemann sums, trapezoidal sums, or showed that, with the same computational effort (same type of formula) we can get better approximations if we don't require the a, to be equally spaced. Simpson's rule depending on their values). Gauss Consider the space P,...
