amplitude is just the height of the sine curve

How do i do that? :/

Maximum value  minimum value divided by 2

How do i work this out? I have no clue

I.e., A regular sine curve has a minimum value at pi/2, equal to 1. At +pi/2, it's value is 1. Thus, you have \[\frac{1(1)}{2}=1\]For your curve, what're the max and min values?

4, 4?

Yes. Now what do you do?

the amplitude is 4, because if you look at the graph.. the amplitude is from zero to the highest point.

or amplitude = distance from middle to either extreme

@bronzegoddess "from zero" is not a solution for all possible sine curves. For example, sin(x)+1, "from zero" has an amplitude of 2, whereas in reality it's 1. @jim_thompson5910 yeah that's right but not rigidly defined.

true, but it's a good way to think about it

it's a basic way at least, if you get too rigorous, then you may confuse things (at least in my opinion)

Well that's why I didn't start getting into domains and formal declarations and such...

lol yeah, don't need to get into those ideas (just yet)

@vf321 its a simple way to think about it sorry if I am wrong.. if I was given an example like sin(x)+1 I would know that the amplitude is 1 because Asinx(BxC)+D, the amplitude is the number before the sin.

@bronzegoddess yes of course no attack intended just didn't want @EmilyJernigan to use that method since she doesn't have the same intuition about it that you do.

its okay, no harm intended on my part too :)

@vf321 do you think you could explain relations to me?

realtions? What do you mean?

Make a question about it and address all points. It's a bit informal doing it on someone else's question.

okay'll switch, I just wanted to know if you could help.
