Find a function of the form y A Sinkx C or y A Coskx C w

Find a function of the form y = A Sin(kx) + C or y = A Cos(kx) + C whose graph matches the function shown below: Leave your answer in exact form; if necessary, type pi for pi.

Solution

Amplitude = 4

A= 4

Period = 0- (-6) =6

k = 2pi/6 = pi/3

Graph passes through origin (0, 0) : C =0

y = 4sin(pi*x/3)
