y= 3 sin 2x

Please explain!!! I do not know how to do this.

**drwls**, Monday, February 1, 2010 at 11:22pmThe amplitude is how far y can increase above (or decrease below) the average value. The average value is zero. The maximum value is 3. The amplitude is therefore 3.

The period is how much x must increase in fr y to return to the original value (regardless of x).

2x must increase by 2 pi for that to happen. Therefore the period is pi
