Problem
Give an example of a periodic non-constant function (with a period 2π) such that it is not infinity or zero for all x (meaning for all x, f(x) is a finite positive number). If such a function does not exist, explain why you think so.

Problem 2 Periodic Force First Cycle The graph at the right depicts the first period of a non-harmonic periodic force (measured in Newtons). This first cycle is described by the piecewise function F(t) below the graph. Per the definition of a periodic function, the function repeats every T seconds. Note that T = 1 s. 1.8 a.
