An observer at notices an aeroplane flying directly overhead at .
Two minutes later, the plane has moved a distance , and is now at ,
with an angle of elevation measuring .
In another two minute, at the same sped, and same altitude, ,
the plane will have moved a distance , and will be at ,
with an angle of elevation measuring .
according to my calculator.
If , as per my calculator,
will be the approximate measure of angle of elevation .
