Answer to a math question During a fishing trip Alex notices that the height h
of the tide (in metres) is given by
h=1−(1/2)*cos(πt/6)
where t
is measued in hours from the start of the trip.
(a) Enter the exact value of h
at the start of the trip in the box below.
At start of trip t=0.
So cos(πx0/6)=cos(0)=1
So h=1-(1/2)xcos(0) =1-1/2=1/2
