Output of (f a b) is bool.When i apply destruct command on if (f a b) then Coq consider it true and then false with
no hypothesis . What command i should apply that in hypothesis it appears as (f a b) =true and
next (f a b) =false also.

destruct (f a b) eqn:Heq will give you Heq : f a b = true or = false additionally.
