The fundamental period of the function f(x)=[x]+[2x]+[3x]+⋯+[nx]−n – InterviewSolution

1.	The fundamental period of the function f(x)=[x]+[2x]+[3x]+⋯+[nx]−n(n+1)2x, n∈N, is ( where [ . ] is the greatest integer function )
Answer» The fundamental period of the function $f (x) = [x] + [2 x] + [3 x] + \dots + [n x] - \frac{n (n + 1)}{2} x, n \in N,$ is $($ where $[.]$ is the greatest integer function $)$
