Use the graph shown at right to write possible equations.

1. Write an equation that is a transformation of sine.

   Hint (a):

   Find the:
   1. Amplitude
   2. Vertical Shift
   3. Frequency
   4. Horizontal Shift.
   
   Substitute the information in:
   $y = a \sin\left(b\left(θ ± h\right)\right) ± k$

2. Write an equation that is a transformation of cosine.

   Hint (b):

   Find the same information above. Substitute in:
   $y = a \sin\left(b\left(θ ± h\right)\right) ± k$
