(b) Both polynomials are equal (to x 33 x + 1), just written in a dierent form. 3.3.1a. Construct a divideddierence table as follows. x = 8 . 3 f [ x ] = f (8 . 3) = 17 . 56492 f [ x ,z ] = f (8 . 3) = 3 . 116256 z = 8 . 3 f [ z ] = f (8 . 3) = 17 . 56492 . 0594800 f [ z ,x 1 ] = = 3 . 134100. 002022222 x 1 = 8 . 6 f [ x 1 ] = f (8 . 6) = 18 . 50515 . 0588733 f [ x 1 ,z 1 ] = f (8 . 3) = 3 . 151762 z 1 = 8 . 6 f [ z 1 ] = f (8 . 6) = 18 . 50515 (See, e.g., Table 3.13 in the text.) The coecients for the Newton form of the approximating polynomial are on the top edge of this table: H ( x ) = 17 . 56492+3 . 116256( x8 . 3)+0 . 0594800( x8 . 3) 2. 002022222( x8 . 3) 2 ( x8 . 6).
