Why is f(t)= 5t2*cos(5000*pi*t) not periodic? Does it not stay at amplitude 2 to2 and oscillates forever?

Best ResponseYou've already chosen the best response.1But because of that t, The amplitude can vary.

Best ResponseYou've already chosen the best response.1Your amplitude is (5t2) right?

Best ResponseYou've already chosen the best response.0I guess the 5t changes the amplitude everytime

Best ResponseYou've already chosen the best response.1Yah so the cosine part is doing the wave. Back and forth back and forth, periodic yes. But then the 5t is linear, causing the wave to move upward.

Best ResponseYou've already chosen the best response.1That 5t causes a vertical pellet thought depending on the value of t.

Best ResponseYou've already chosen the best response.0so periodic it has to be a constant pattern can't keep changing

Best ResponseYou've already chosen the best response.0I see it now thanks for your guys' help wish I could give both of you best answers

Best ResponseYou've already chosen the best response.1Yah periodic would mean it REPEATS. Yes the PATTERN is repeating, but the values are not. The values keep getting larger and larger. I can see how that might be confusing though :)
