You know the definition of "periodic" don't you? If f is periodic with period p, then f(x+ p)= f(x) for all x. If g is periodic with periodic p, then g(x+ p)= g(x) for all x.
So what can you say about ?
Demonstrate Period of trigonometric functions?
Prove that if f and g are periodic with period p, then f/g is also periodic,
but its period could be smaller than p.
Help me, Ido not know how complete this exercise, what I should do here, can someone please explain?
