Answer» Correct Answer - A `(fogogof) (x)= sin^(2) (sin x^(2))` `(gogof) (x) = sin (sin x^(2))` `:. Sin^(2) (sin x^(2))= sin (sin x^(2))` `rArr sin (sin x^(2)) [sin (sin x^(2))-1]=0` `rArr sin (sin x^(2))=0` or `1` `rArr sin x^(2) = npi` or `2 mpi+pi//2`, where `m, n in I` `rArr sin x^(2)=0` `rArr x^(2) =n pi rArr x= pm sqrt(npi), n in {0, 1, 2, ...}`. |
