Write one equation in terms of sine and one equation in terms of cosine for the graph shown at right.
Where is the midline of the curve? This is the vertical shift of the function.
Added to original periodic curve, horizontal line at, y = 1.
What is the amplitude?
Added: Vertical segment from horizontal line, y = 1, to second turning point.
What is the simplest horizontal shift for the sine?
Added: highlighted point at, (pi, comma 0).
What is the simplest horizontal shift for the cosine?
Added: highlighted point at, (negative 1 half pi, comma 4).
