ChE 348 Homework # 8 ___________________________________________Due: Thursday, 04 November 2010 Numerical Integration (Trapezoidal and Simpson rules) 1. Compute by hand T 4 (f) and S 4 (f) for the integral 295836867 . 1 2 3 ln 3 ln 3 1 = = = dx x I Compare the errors I – T 4 and I – S 4 . 2. Evaluate ( by hand ) the integral of the following tabular data with (a) the trapezoidal rule and (b) Simpson’s rules: x -2 0 2 4 6 8 10 f(x) 35 5 -10 2 5 3 20 3. Integration provides a means to compute how much mass enters or leaves a reactor over a specific time period, as in
