Finding period of any type of function

Click For Summary

Homework Help Overview

The discussion revolves around finding the period of various functions, specifically those involving trigonometric functions combined with the greatest integer or floor function. Participants explore the periodicity of functions like f(x) = tan(πx) + x - [x] and f(x) = sin(2πx) + x - [x], considering different forms of the greatest integer function.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • Participants discuss the definition of periodicity and how to verify it in complex functions. There are attempts to graph functions to understand their behavior better, and questions arise about the implications of combining periodic functions and the potential for cancellation of terms.

Discussion Status

Some participants have provided insights on graphing techniques and the nature of periodic functions, while others are exploring the implications of combining different periodic functions. There is ongoing exploration of examples to clarify the concepts being discussed, but no consensus has been reached on the broader implications of the conjectures presented.

Contextual Notes

Participants are grappling with the definitions and properties of periodic functions, particularly in the context of sums of functions with different periods. The discussion includes considerations of how to approach examples and the challenges of proving general statements about periodicity.

That explains it all. Thank you everybody.

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.
