Well, we know this is a sine graph, so the basic shape is up, stop, down, stop, up, and finally stop. (Horrible attempt at me trying to describe the nature of a sine graph). Okay so if this is a sine graph, then we must start at the origin right? Also the amplitude is 5, wait what does this mean again? Oh yah,
ampli-tude = how tall are you, dude? so the highest point will be 5, and the lowest point will be -5 on the sketch. The period is
, so after every
minutes, we have to repeat the graph! Also at every
minutes, we will see something special going on.
