Dear Aditya
Cos 2(pi/4 + 2x)
= Cos (pi/2 +4x)
= - sin4x
Now range will be [-1, 1]

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
