The definition of the function SymbolicSum is given as In[79]:= ?SymbolicSum SymbolicSum[f, {i, imin, imax}] attempts to find the value of Sum[f, {i, imin, imax} ] for symbolic imin,imax. SymbolicSum[f, {i, imax}] evaluates the sum -------------------- of f with i running from 1 to imax. Even though the rule "symbolic imin,imax" is broken in the second sentence, the WRI has a point there. cetin
