    amplitude = -4; period = 2π; phase shift: x = -PI/2 amplitude = -4; period = π; phase shift: x = PI/2 amplitude = 4; period = π; phase shift: x = -PI/2 amplitude = 4; period = 2π; phase shift: x = PI/2

    actually the phase shift should be negative

    since 2x + pi turns into 2x - (-pi)

    C/B = (-pi)/2 = -pi/2
