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)
