use x=1.5 and h=0.1

Use forward and backward difference approximations of O(h) and a centered difference approximation of O(h^2) to estimate the first derivative of the function examined in Prob. 4.5. Evaluate the derivative at x=1.5 using a step size of h =0.1. Get percent relative error with the true value of the derivative. Interpret your results on the basis of the remainder term of the Taylor series expansion.

4.7 Use forward and backward difference approximations of O(h) 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
