Statement I: x=kπ13x=\frac{k\pi}{13}, k∈Zk\in\mathbb{Z}, does not represent the general solution of the trigonometric equation sin⁡13x−sin⁡13xcos⁡2x=0\sin13x-\sin13x\cos2x=0. Statement II: Both x=rπx=r\pi, r∈Zr\in\mathbb{Z}, and x=kπ13x=\frac{k\pi}{13}, k∈Zk\in\mathbb{Z}, satisfy the trigonometric equation sin⁡13x−sin⁡13xcos⁡2x=0\sin13x-\sin13x\cos2x=0.
