Include a Matlab code as well 2. We wish to integrate f(u) = 1/[k (1 - "N)], (with constants k = 0.25 and N = 4000) from u= uj = 0.6931 to u= u2 = 7.6009 using Monte Carlo method with the following simple variable transform: u = (u2 – ui) y + ui and du = (u2 – U1)dy. Calculate this integral with 10000 random numbers. (Exact answer: 30.4018)
