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

But because of that t, The amplitude can vary.

Your amplitude is (5t-2) right?

I guess the 5t changes the amplitude everytime

Yah 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.

That 5t causes a vertical pellet thought depending on the value of t.

so periodic it has to be a constant pattern can't keep changing

I see it now thanks for your guys' help wish I could give both of you best answers

Yah 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 :)
