Answer 23

Annnyyyway, here's what a trigonometric function looks like\[{\rm amplitude} \times \sin(\omega \times t) \]

Answer 24

Or\[\rm amplitude \times \cos(\omega t)\]

Answer 25

The period/frequency of the periodic function is given by\[\dfrac{\omega}{2\pi}\]

Answer 27

Solving these questions may require a little extra knowledge of a sine wave.

For example, do you know that the maximum of \(\sin(x)\) is \(+1\) and the minimum is \(-1\)?

Answer 28

We can start from just this basic point, and reach places.

Answer 29

If the maximum and minimum of \(\sin(x)\) are \(+1\) and \(-1\), how do you think it would be for \(2\sin(x)\)? What are the maximum and minimum for that?

Answer 30

Yes...! Because +1, the maximum for sin(x), is multiplied by 2 to get the max of 2 sin(x). Do you see where I'm going?

Answer 31

What would it be like for \(2\sin(x) +1\)?

Answer 32

Nope, nope. :)

What is the max of \(2\sin(x) + 1\)?

Answer 33

Yes!

Answer 34

same.....its ok

Answer 35

what grade r u in @chaser71
