A student attaches one end of a rope to a wall
at a fixed point 3 feet above the groud, as
shown in the accompanying diagram, and
noves the other end of the rope up and down.
producing a wave described by the equation
y = a sin bx + 6. The range of the rope's
height above the ground is between 1 and 5
feet. Write
the equation that represents this wave.
