```							i can see that the thiird question is quite tricky indeed. we need to OBSERVE that root3cosx+sinxor root3cosx+sinx – 2however, root3cosx+sinx – 2 should be greater than zero for the under root sign to make sense.. so, root3cosx+sinx>=2. these both conditions can be true iff root3cosx+sinx=2or sin(x+pi/3)=1=sin(pi/2)or x= n*pi+(-1)^n*(pi/2) – pi/3
