The solution to section 1.3, #1a that I handed out was wrong. The code I sketched was right, but the numbers weren't. And the graph was also wrong. If you plot the two polynomials against each other, they look identical (since the largest error is like 10^(-7)). Here are the correct numbers: >> x x = Columns 1 through 6 0 1.0000e-01 2.0000e-01 3.0000e-01 4.0000e-01 5.0000e-01 Columns 7 through 11 6.0000e-01 7.0000e-01 8.0000e-01 9.0000e-01 1.0000e+00 >> p6 p6 = Columns 1 through 6 1.0000e+00 9.9944e-01 9.9778e-01 9.9501e-01 9.9115e-01 9.8621e-01 Columns 7 through 11 9.8021e-01 9.7317e-01 9.6512e-01 9.5608e-01 9.4608e-01 >> p8 p8 = Columns 1 through 6 1.0000e+00 9.9944e-01 9.9778e-01 9.9501e-01 9.9115e-01 9.8621e-01 Columns 7 through 11 9.8021e-01 9.7317e-01 9.6512e-01 9.5608e-01 9.4608e-01 >> p6-p8 ans = Columns 1 through 6 0 -3.1086e-15 -7.8393e-13 -2.0089e-11 -2.0067e-10 -1.1961e-09 Columns 7 through 11 -5.1429e-09 -1.7651e-08 -5.1371e-08 -1.3181e-07 -3.0619e-07
