Consider the functions FG: RR F()co(()co() The gaol of this HW is to develop several methods to compute F(x)dx, with a good precision, methods priorly tested on the function G 1) Let n be an integer. Define the nodes on 1-1, 1] such that 2j-Xjt1-Fj-2 (nodes are uniformly distributed). For each j 0, ,n1 choose ay e [x, z+i]. Develop a Matlab code to compute (the Riemann's sum) for n 5, n 10
