given : use 4.5 to solve 4.8 in matlab.
r a - 4.8 Use a centered difference approximation of O(h) to estimate the second derivative of the function examined in Prob. 4.5. Per- form the evaluation at x = 2 using step sizes of h = 0.25 and 0.125. Compare your estimates with the true value of the second deriva- tive. Interpret your results on the basis of the remainder term of the Taylor series expansion. lavni non ha حطه
4.5 Use zero- through third-order Taylor series expansions to predict f(2.5) for f(x) = 25x – 6x² + 7x - 88 using a base point at x = 1. Compute the true percent relative error € for each approximation.
