This regards not only Calculus`Integration`, but also the built-in Integrate: Defining a square wave... In[1]:= ondQua[t_] := If[OddQ[Floor[2t]], -1, 1] ....Mathematica fails completely in computing its defined integral... In[2]:= Integrate[ondQua[t], {t, 0, 1}] Out[2]= 1 ....without any warning or error message !!! How is it possible? With NIntegrate the things goes better, but i believe that a similar risk with Integrate would have to be documented somewhere; if exists some notes about this using of Integrate on Mathematica-help, please tell me where. Waiting your answers, Thanks, Raf.
