Cousin Throckmorton has gone into hiding to escape online publicity. He has taken a room in a downtown hotel under the alias CT, and nervously reveals the room number to trusted family members only by
telephoning them and playing a secret tone, whose waveform reveals the curve y = f(x) shown below. Only you know that CT's room number is the 4-digit sequence b₁b₂bb, in which each digit b, satisfies
bx = f(x) sin(kx) da,
k = 1, 2, 3, 4.
Use the given information to find CT. He is counting on you.
