Hi crosser43,

In , b indicates the period of the sine curve.

In , the period is 2.

The period of the sine curve is the length of one cycle of the curve. The natural period of the sine curve is . So, a coefficient of**b**=1 is equivalent to a period of .

To get the period of the sine curve for any coefficient**b**, just divide by the coefficient**b**to get the new period of the curve.

So, the period of is

The coefficient**b**and the period of the sine curve have an inverse relationship, so as**b**gets smaller, the length of one cycle of the curve gets bigger. Likewise, as you increase**b**, the period will decrease.

The zeros of the curve in the interval are .

Just click on the attachments. They should clear up (I hope).
