The process begins by approximating integral of function f(x) = 1=x on interval [n; n+1] using Lobatto Quadrature. Then the approximation of the integral is related to the analytic result of the integral of f(x) = 1=x on the interval [n; n+1]. Approximating the Euler constant e using Lobatto quadrature method are done on some variations of node points. At the end of the discussion the comparison on approximating the Euler constant e using trapezoidal rule, Simpson 1=3 rule, Gauss quadrature rule and Lobatto quadrature method are givenenEstimating the Euler constant eLobatto quadrature methodtrape- zoidal ruleSimpson 1=3 ruleGauss quadrature rulestudent Paper Post Degree
