In each formula make t the subject and put your answers equal to one another.
A sporting airplane is flying such that its height varies with time in accordance with the formula
y = 10 + 3/(t0 + t)2, whereas its horizontal distance varies with time as x = (t0 + t)2, where t is in seconds, and x and y are in metres, t0 = 1 sec.
(a) Find the trajectory of the airplane y as a function of x.
(b) What is the function, describing the trajectory?
