The altitude H H\,H of a research drone, measured in kilometres, is modelled by the curve C C\,C with equation H=f(t)H = f(t)H=f(t) for t>0t > 0t>0, where t t\,t is the time in hours since it reached a specific tracking station.
Given that
find the equation of the normal to C C\,C at PPP, giving your answer in the form H=mt+cH = mt + cH=mt+c where m m\,m and c c\,c are constants to be found.
find f(t)f(t)f(t), giving each term in simplest form.
