Compute the backward and center difference approximations for the 1st derivative of y = log x evaluated @ x=20 and h=2. Using the second order error O(h2) formula.
(b) Derive a numerical differentiation formula of order O(h4) by applying Richardson ertrapolation to 2 MI 2h 120 Richardson extrapolation is a useful way to obtain higher precision from either an approximate formula or a code, provided you know precisely what the truncation error of the approximation is. The truncation error is of order h2 above. So what we will do is use the above formula over rth/2 to derive another approximation for the first derivative. The add/subtract these two...

Derive the forward difference scheme and central scheme for the first order derivative. Comment on the difference of the numerical accuracy for the two schemes.
Use forward and backward difference approximations of O(h) and a centered difference approximation of O(h2) to estimate the first derivative of the following function:f(x)=25x³-6x²+7x-88Evaluate the derivative at x=2 using a step size of h=0.25. 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.
