In the attachments, I've built up the function step by step.
The first shows . This is a single cycle of a sine wave for values of from to . Note that has values between .
The second shows ; in other words , with . You'll see that the difference is that now needs to take values from 0 to 4 to give one complete cycle. So gives the wavelength of the sine wave.
The third graph shows . So I've given the value in your formula . If you look closely, you'll see that the graph has been shifted units to the right. So gives the phase-shift.
Graph #4 is . So I've put . You'll notice that now takes values between . So is the amplitude of the sine wave.
Finally, I've shown you the graph of . So I've put . You'll see that now takes values between and , the graph having been shifted upwards by unit. , then, is the vertical shift.
