Work harder. It will help along the line if you are thinking about it in the right way.

Good evening Sir,
periodicity of {x} (fractional part function) is one.but how can we so sure that in interval . {1/x}will follow one particular behaviour. I mean to say that it can decrease or increase so can cut {x^2} at more that one point.
