     integer is of the form 9m, 9m+1 or 9m+8

5. Prove that Sec⁴ A – Sec²A = Tan⁴ A + Tan² A

6. A straight highway leads to the foot of a tower. A man standing at

    the top of the tower observes a car at an angle of depression of  

   30⁰, which is approaching the foot of the tower with a uniform

   speed. Six second later, the angle of depression of the car is found

   to be 60⁰. Find the time taken by the car to reach the foot of the

   tower from this point.
