What happens if you change the amplitude to 2? Below is the graph of  y = 2 sin x.


















               You see how the graph stretched up right? Now the range is [-2, 2] instead of [-1,

               1].


               What do you think would happen if you changed the amplitude to ½? Or 3?

               Check it out below






















               Does this happen with cosine as well? Recall the graph of y = cos x
