How are periodic phenomena relatively easy to model using trigonometric functions? what makes them difficult to model this way? explain your reasoning and cite examples where possible.

step-by-step :

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
