1. Use the method of undetermined coefficients to compute the coefficients of a finite difference approximation for u'(E) using the values u(0),u (1) and u(2). Choose the coefficients such that the formula is exact for polynomials with degree less or equal to 2. Can you use these ecoefficients to get an approximation for a first derivative based on function values v(r),v(x+h)and v(x +2h)? At which point z and for which functions v(a) is this approximation equal to '()? Determine the...
