 Author Comment/Response BB 01/18/13 1:57pm Strange issue with NIntegrate: In[100]:= NIntegrate[F[s3, s1], {s3, 0, 28}, {s1, 0, 28}, Method -> "LocalAdaptive"] Out[100]= 863.411 In[101]:= NIntegrate[F[s3, s1], {s3, 0, 27}, {s1, 0, 28}, Method -> "LocalAdaptive"] Out[101]= 863.446 In[102]:= NIntegrate[F[s3, s1], {s3, 27, 28}, {s1, 0, 28}, Method -> "LocalAdaptive"] Out[102]= 0. I was hoping to find Out[100] = Out[101] + Out[102]. F is a complicated function, however, F[x, y] = 0 for x > 23. This is confirmed by checking: In[106]:= F[23, y] Out[106]= 0 In[108]:= F[27, y] Out[108]= 0 etc. Can someone please comment on what could possibly be wrong? URL: ,
