thanks guys but actually I am little confuse now because one says its periodic and other says its not.

Thanks, still waiting for your pics to be approved. So just to be sure, when you see periodic changes it means that the function is NOT periodic right? And I know that its easy to conclude the answer from a plot but is there an simple arithmetic proof? and thanks a lot.!

I need to find if Sin(x^2) is a periodic function. As I think its not periodic but I need to proof that. I know that its possible to use f(x) = f(x+T), while T is the period frequency. But how to find out T ? and how to contradict this equation to say that the function is not periodic...
