Dear Ary, Your question is a bit difficult to interpret. Sin[x y] has maxmin = {-1,1} for x and y reals. However, I believe this example my help you out. It will find "some" of the maxima, but not all. FindMaximum[(1 + Sin[x y])/(2 + Cos[y]), {{x, 1}, {y, 2}}] Here x and y will be real numbers. To find all max/min--inima, you could take derivatives symbolically and Solve symbolically Cheers, Craig On Thu, Apr 10, 2008 at 2:14 AM, Ary Adilson Morales Alvarado < amorales at lme.usp.br> wrote: > Dear friends, > > How I can to obtain the maximum and minimum values in a function like a > Sin, but that varying their frequency with the time. > > Thanks in advanced, > > Ary > > > > -- > This message was scanned for spam and viruses by BitDefender. > For more information please visit http://linux.bitdefender.com/ > > > -- W.
