WebWe know that cos a - b = cos a cos b + sin a sin b so, by replacing a by 4 θ and b by θ in the above equation we get, Since it is given that θ = π 5, substitiute θ as π 5 in the above equation. Therefore, the value of d e t B is 1. 381966 which lies between 1, 2. Hence, option (B) is the correct answer.
