My question is:

A girl is swinging on a swing. She continues to swing, but than stops. Is this periodic? I know the swinging is, but does it matter that she stopped?

Also is the stop a function?

Thanks, hopefully that make sense.
 
...and this is grade 11 math :?:
When does one get on the ferris wheel?

It's likely an exercise intended, within the context of a trig class, to help students get a sense of what "periodic" means.

However, the answer may depend upon the book's particular definition of "periodic". I think this would be "damped periodic" motion, and that might not work with the book's definition.

Hello, needshelp!

Could you state the original problem?

The problem raises even more questions . . .

A girl is swinging on a swing.
Define "swinging".
Is she 'pumping' to maintain her momentum and amplitude?
Or after being push-started, is she sitting passively?

She continues to swing, but than stops.
"Continues to swing" -- how? . Pumping or passive?

Define "stops".
Does she sit passively until the swing comes to rest (which could take a whilte)?
Or does she jam her heels into the ground and stop like Wile E. Coyote?

Is this periodic?
I know the swinging is, but does it matter that she stopped?
Is what periodic?

You know that the swinging is periodic . . . so what else is there?

Also is the stop a function?
Define "functtion".
