Derive the formula in Prob. 29 from (14)

Data from Prob. 29

The derivative f'(x) can also be approximated in terms of first-order and higher order differences.

(4fo-% f'(xo) - I,v² - %v +

Compute f'(0.4) in Prob. 27 from this formula, using differences up to and including first order, second order, third order, fourth order.

Data from Prob. 27

Consider f(x) = x4 for x0 = 0, x1 = 0.2, x2 = 0.4, x3 = 0.6, x4 = 0.8. Calculate f'from (14a), (14b), (14c), (15). Determine the errors. Compare and comment.
