Problem 1:
Here is a set of polynomials
{1,1-x}.
Is this a linearly independent or dependent set, and why?
Show that this collection of polynomials is orthogonal with respect to
the weight function w(x) = exp(-x) on (0, ∞). Show your working, you should not
just plug integrals in to a software-solver.
(c)
Hence find the least squares polynomial
P(x) = aogo(x) + aigi(x)
for f(x) = e, where {go(x), g1(x)} = {1,1-x}. Show your workings.
