Hi Student
Domain of sin-1x is between [-1,1]
=> -1 < [2-4x2] <1
-1< [2-4x2]
this means -1<2-4x2< 0 (for above to be true)
=> -3<-4x2<-2
=> 3>4x2>2
=> 3/4> x2> ½
Similarly you can solve the other inequality [2-4x2]<1 by taking 0<2-4x2 <1

and find the common solution

If you still are having please reply on this thread.
