Best ResponseYou've already chosen the best response.0amplitude is just the height of the sine curve

Best ResponseYou've already chosen the best response.1I.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?

Best ResponseYou've already chosen the best response.0the amplitude is 4, because if you look at the graph.. the amplitude is from zero to the highest point.

Best ResponseYou've already chosen the best response.1or amplitude = distance from middle to either extreme

Best ResponseYou've already chosen the best response.1@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.

Best ResponseYou've already chosen the best response.1true, but it's a good way to think about it

Best ResponseYou've already chosen the best response.1it's a basic way at least, if you get too rigorous, then you may confuse things (at least in my opinion)

Best ResponseYou've already chosen the best response.1Well that's why I didn't start getting into domains and formal declarations and such...

Best ResponseYou've already chosen the best response.1lol yeah, don't need to get into those ideas (just yet)

Best ResponseYou've already chosen the best response.0@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.

Best ResponseYou've already chosen the best response.1@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.

Best ResponseYou've already chosen the best response.0its okay, no harm intended on my part too :)

Best ResponseYou've already chosen the best response.1Make a question about it and address all points. It's a bit informal doing it on someone else's question.
