Hi All : I am also interesting in the solution of how to make an asumption in Mathematica. I can't find any method in Mathematica. If anybody has the approch to do this , please send it to my e-mail too , Thank you all .. j_m_1967 at hotmail.com (JM) wrote in message news:<ah8otr$aut$1 at smc.vnet.net>... > I know that this should be 0 but why can't I get mathematica to think > likewise. > > > In[4]:= Limit[Sin[a*x]/(a*x),x->Infinity] > > Sin[a x] > Out[4]= Limit[--------, x -> Infinity] > a x > > Is the problem a?
