RE: Numerical integration vs. integrals that are zero
Excel simulation, sin(x), x = 7 to 367 degree, u transformed integral:

Code:
n    Simpson  Romberg extrapolation
1 -43.872964
3   7.312644  10.725017
7   0.001692  -0.485705  -0.663653
15 -0.000424  -0.000565   0.007136  0.009766
31 -0.000007   0.000021   0.000030  0.000002  -0.000007

It is likely area algorithm is not Romberg extrapolation.
