1. The problem statement, all variables and given/known data If ## f(x) = sin^2x + sin^2(x+ π/3) + cosxcos(x+ π/3) ## and $$g(5/4)=1$$, then ##(gof)(x)## is equal to? Options are 0 1 sinx None of these 2. Relevant equations I know gof(x) is g(f(x)) but here g(x) is not given. 3. The attempt at a solution Basically I think we have to put f(x) value in g(x) but here g(x) is not given, What's the use of g(5/4) ?
