    "The key point is to realize that our $g(p)$ depends *quadratically* on $p$, and a center-difference approximation is *exact* for a quadratic function *in exact arithmetic*.   So, *all* of the difference arises due to roundoff errors.  In the finite-difference approximation, the difference $g(p + \\delta e_n) - g(p - \\delta e_n)$ is the difference of two nearly equal quantities as $\\delta \\to 0$, so there is a large cancellation error in the result (i.e. the result arises from the *least* significant digits of $g$), and hence the error worsens with decreasing $\\delta$."
