1.Let θ=π5\theta = \dfrac{\pi}{5}θ=5π and A=(cosθsinθ−sinθcosθ)A = \begin{pmatrix} \cos\theta & \sin\theta \\ -\sin\theta & \cos\theta \end{pmatrix}A=(cosθ−sinθsinθcosθ). If B=A+ATB = A + A^{T}B=A+AT, then det(B)\det(B)det(B):a.is 111b.lies in (1,2)(1, 2)(1,2)c.is 000d.lies in (2,3)(2, 3)(2,3)Login to continueOnly logged in users canattempt or see the solution.
