Lesson 31

In this lesson we learnt an easier way of graphing periods

Sin and Cos graphs when you have 2π upstairs and a # downstairs,  the number will be your period. 
example:
y= cos 2π/4 Ѳ
P= 4  1/4p= 1
Same goes for Sin as well

For a Tan graph when you have a π upstairs and a number downstairs, the number is your period.
example:
y=tanπ/4 Ѳ
P=4 1/4p= 1
