Finding period of any type of function

[Raghav Gupta]

That explains it all. Thank you everybody.

 

[K V N Murty]

period of tan pi x = 1 as the graph for x = -1/2 to 1/2 repeats.
period of x - [ x ] = 1 as the graph repeats for [n , n-1).
Hence, the period of the given function is 1.

AGain for Sin (2 pi x ) + x - [x] also the period is 1, for a similar reason.
