Given: use to solve for 4.7. use matlab.
f meaning of the 4.7 Use forward and backward difference approximations of Oſh) and a centered difference approximation of O(h?) to estimate the first derivative of the function examined in Prob. 4.5. Evaluate the derivative at x = 2 using a step size of h=0.2. Compare your results with the true value of the derivative. Interpret your results on the basis of the remainder term of the Taylor series expansion. J:ffnunna annnavimation of 2) to estimate r r
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.
