Use the MATLAB "format long e" command to display your numeric results with 15 precision digits. Consider the riemann's zeta function 3 (x)= 2X=1 K* 1 Value is approaching of 3 (x) through the sequence of partial sums , and it denotes by en:=3(x) - Sn the error of this approximation. 1 SEXK=1 k* 1) Considere the function t -* with x > 1, to prove that Reis St-* dt = -1 (k-1)+2_VK 22. I No induction needed 2) Show the following quota for the error O Sens Use this quota to get n E N that guarantees a minor error than 10-9 when x=1.1, don't asked to approach S(x). 1 1 7*-1 3) Include routine implementation "[zL,zR] = zetaRiemann(x.n)", in matlab, which one return the approximation of (x) through the sum Sn, which is calculated by two different ways: Z is calculated accumulating on the left, that is, 22= (...((1+2)+5+) +...). Zr is calculated accumulating on the right, that is, 2x = (1+(+...+ + ...)). (n-1) 4) Using others techniques it is known that the exact value of g (2) = . Use your routine to approximate
