Note that for `y=Acos(B(x-h))+k` the amplitude is `A` , the period is `(2pi)/B` in radians, or `360/B` in degrees, the phase shift(horizontal translation) is `h` , and the vertical displacement is `k` .
(1) The amplitude is `sqrt(7)`
(2) The period is `360/5=72`
(3) The phase shift is 85 to the right
(4) The vertical displacement is 1.2 down
