Excel question

0.5 2) Use EXCEL to evaluate the approximate value of the above integral using trapezoidal rule with:n-2 4, 8 and 16 The true solution is: 0.478306. Compute the percentage error, where E l(analytical numerical) 100 /analytical solution]. Demonstrate convergence, which shows that the error decreases when you used more trapezoids. 3) Use EXCEL to compute value of the above (problem 2) integral using the Simpson's rule with n- 2,4,8 and 16: compute the error and demonstrate convergence Compare the error values estimated using n-2,4,8, 16 in problems 2 &3 and comment on the results
