1. The two-point forward difference quotient with error term is given by where ξ e ll, l + hl. In class we showed an additional error term appears to due to computer rounding error, e(r). Denoting (z) f(x) +e(x) as what the com- puter stores, and supposing f"(x)M and e() e where e, M are constants, we obtained an upper bound for the error between f(r) and the computed forward difference quotient 2c h Find the minimum value of the...
