Hi,
If you have the definition of the function for one period, then you can use
Mod to use this definition elsewhere
for example, say that the period is Pi/3, then

f[t_]:=Sin[Mod[t,Pi/3]]
will be a periodic function
and in general,
replace t with Mod[t,T] everywhere in the definition of your function where
T is the desired period
