It's the same for Integrate, Sum, and other such functions. For example: In[1]:= Sum[Exp[-k]*Sin[k^2], {k,1,Infinity}] 2 Sin[k ] Out[1]= Sum[-------, {k, 1, Infinity}] k E In[2]:= N[%] NIntegrate::ncvb: NIntegrate failed to converge to prescribed accuracy after 7 recursive bisections in k near k = 22.3143. Out[2]= 0.218384 Bhuvanesh, Wolfram Research.
