we can but not by the limits method of integration that we know.
But this is not in syllabus...
It is about definitions...

i dont think u can srinath. just think once more.
@sky and mka: dirichlet is a very famous function. it is discontinous at every point of its domain{also called as nowhere continous function}. and coming to its form, its a limit of another limit noth taken n→∞

wiki gives a nice thign looks a bit scary at first then the understandnig of the complex( so called ) function is interesting.

btw the value is zero..
you can think of it as that almost everywhere the function's value is 0
but at some of the points it is non zero.
the probability of finding a zero wala point is 1
so the area will be zero..
Thisis a very crude way to understand that the integral is zero..
This is not in syllabus.
