Now, as a word problem maybe it rings a bell, right?
-
Do you know such a function?

Exponential is good.

Another one? Yes?
-
Trigonometric functions are good.

So I'm going to temporarily dismiss the exponential.
-
I will tell you why.
-
An exponential function is actually a very good guess.
-
You can say x = e^t, for example.
-
The trouble is,
-
this is growing exponentially,
-
and we know this spring mass system,
