Sketch the graph of a wave with a period of 2 and an amplitude of 4

Answer 1

I know that the peak and the trough will be at 4...i just don't know where the period would be....

Answer 2

@perl @dan815

Answer 3

That's what a period of 2 looks like. Any wave that takes 2 units to complete a cycle

Answer 4

Ok and the amplitude I got right? right? the peak and the trough need to be at 4....

Answer 5

Amplitude is half the distance between peak and trough, so there has to be 8 units between them.
If your peak is at 4, then the trough has to be at -4.
If your trough is at 4, then the peak has to be at 12.
