My package calcE does this automatically when both endpoints are multiples of Pi (incl zero), and a simple option (UsePi->{True,False}) does it otherwise. For example, PlotE[Sin[x],{0,2Pi}] will place tick marks at multiples of Pi. Check out http://seuss.math.wright.edu/calcE/calcE.html for an example and further information. > Also, does > mathematica by any chance able to figure out the period > for a function(or the amplitude for that matter).

The period of Trig(c x) is (2pi)/c, where Trig is any trigonometric function. This covers >=95% of the cases that come up. Richard Mercer
