The graph of one complete period of a sine or cosine curve is given in the attached document.
a) Find the amplitude, period and phase shift.
b) Write an equation that represents the curve in the form:
y = a sin k (x - b) or y = a cos k (x - b)
44. amplitude = 3, period = 4?, phase shift = 0, no shift
K = 2pi/(4pi) = 1/2
The expert finds the graph of a sine of cosine curves.
