Exercise 4.6-2: Find the optimal value for h that wll minimize the error for the formula f' (xo) = f(x0+h) _ f(xo) _ h f"(e) in the presence of roundoff error, using the approach of Section 4.6 a) Consider estimating f(1) where f(x)using the above formula. What is the optimal value for h for estimating f'(1), assuming that the roundoff error is bounded by E-10-16 (which is the machine epsilon 2-53 in the 64-bit floating point representation). b) Use Julia...

4. The first derivative of a function f(x) at a point x = xo can be approximated with the four-point central difference formula: dx 12h where h is a small number relative to xo. Write a user-defined function function that calculates the derivative of a math function fx) by using the four-point central difference formula. For the user-defined function name, use dfax-FoPrder(Fun, x0), where Fun is a name for the function that is...
Please answer question #1
and write legibly - I have also equation 4.6 from
the textbook. Thanks
1. In class, we derived the Central Difference formula for f'(x0) as f'(x) = f(xo + h) – f(20 - h) +002). f'(o)= 2h A similar result, where four points are involved and the error is (h"), is given in the textbook, page 176, Equation (4.6). Prove it. Five-Point Midpoint Formula • f'(xo) = [f(xo – 2h) – 8f (xo – h) +8f...
