Unformatted text preview: f ( x ) = e x in the interval [0 , 1]. What is the error in your approximation? How could one get a more accurate formula? Additional problem 2: Some of you might be familiar with the formula: n X i =1 i := 1 + 2 + + n = n ( n + 1) 2 . We want to generalize this formula to the sum of squares. Assume that there exists a polynomial, p ( x ), such that n X i =1 i 2 := 1 + 2 2 + + n 2 = p ( n ) . Use Newtons interpolation to nd this polynomial. Check your answer by computing the sum of the rst 100 squares. 1...
