Unformatted text preview: f ( x ) = x sin x is approximated by a polynomial of degree nine that interpolates our function f at ten points in the interval [0 , 1], then show that the error is less then 30 . 8 × 107 on this interval. ( 8 points ) 5.4. (Bonus) Let x , x 1 , x 2 , . . . , x n be arbitrary integers, x < x 1 < x 2 . . . < x n . Show that every polynomial of n th degree of the form x n + a 1 x n1 + a 2 x n2 + . . . + a n assumes at the points x , x 1 , x 2 , . . . , x n values, at least one of which is of absolute value ≥ n ! 2 n .
