Question : Determine whether the function is periodic. If it is ...
WebIf the periods of two periodic functions do not have a common multiple, then their sum is not periodic. Perhaps the simplest example is $\sin(x) + \sin(\pi x),$ whose terms have least periods 2π and 2 respectively. in your case period of first function is $2*\pi/2=\pi$ and period of second function is $2*\pi/8=\pi/4$ WebOct 26, 2015 · All continuos time signals are periodic signals.

Periodic Functions and Fourier Series 1 Periodic Functions A real-valued function f(x) of a real variable is called periodic of period T>0 if f(x+ T) = f(x) for all x2R. For instance the functions sin(x);cos(x) are periodic of period 2ˇ. It is also periodic of period 2nˇ, for any positive integer n. So, there may be in nitely many periods. WebJul 2, 2024 · The answer is actually "true"; at least, the derivative of any differentiable periodic functions is periodic. This is easy to prove: Suppose f: R → R is a differentiable periodic function with period P. Let g: R → R be the function g ( x) = x + P. Then f = f ∘ g so f ′ = ( f ∘ g) ′. By the chain rule, for all x ∈ R we have. swan hill accounting
