Hi, my prob is find the most accurate 1st derivative of f(x)=exp(cos(x)) at x=1, with h=0.5,0.25,..,2^(-16). I calculate the 1st der. using 1st order central diff formula & trying to improve the accuracy using Richardson extrap. got incorrect result
clear; clc; format shortG f = @(x) exp(cos(x)); df = @(x) -exp(cos(x))*sin(x); x = 1; Truef1 = df(x); A = []; h = 1/2...
