1. Translations of Trig Functions
We work with sin , cos only
Vertical Shifts
y = cos + 2

2. Horizontal Shifts
2 y = sin ( + )

3. Vertical/ Horizontal Stretch/ Compress
ex. f(x) = 2cosx

4. Horizontal
ex. f(x) = sin(2x)
new period
ex. Graph y = sin(x) New period

5. y = 2cos(x - ) - 1
y = 3sin2(x + ) - 1
