To find the period of a CosѲ and SinѲ you can use the formula 2π/ k k: the number in front of x or Ѳ
To find your quarter period you take your period and divide it by 4
The way you find the scale is use the common denominator for the period and the 1/4 period
To find where you start on the graph if there is a phase shift, you put your phase shift over the denominator of the scale
