2. Graph the functions f(x)x(x 1)(x-2) ..(x- k) for k- 1,2,..,10. (These are examples of the polynomials occurring in the error formula for polynomial interpolation.) We want to produce an evenly spaced table of values for the function f(x) sin(x) for x E [O,T/2] such that, with cubic interpolation, we can give the values of the function at any point in the interval with an error less than 5 10-12. That means finding a number n such that with h-/2n...

The Taylor polynomial approximation pn (r) for f(x) = sin(x) around x,-0 is given as follows: TL 2k 1)! Write a MATLAB function taylor sin.m to approximate the sine function. The function should have the following header: function [p] = taylor-sin(x, n) where x is the input vector, scalar n indicates the order of the Taylor polynomials, and output vector p has the values of the polynomial. Remember to give the function a description and call format. in your script,...
