3 is the amplitude since its all out in front

and the period is a normal sin period of 2pi

isn't 2pi the period of sinx?

So I am still confused on how to find the period of the graph?
amistre64
  • amistre64
sin(x) is nekkid so you just use its normal period; its normal cycle time of 2pi
amistre64
  • amistre64
sin(2x) means that the period is twice as fast and only take 1/2 the time to make a complete cycle; sin(2x) has a period of 2pi/2 = pi
amistre64
  • amistre64
sin(pi x) has a period of 2pi/pi = 2
