What is sin⁡0\sin 0sin0?

A

cos⁡θ=0\cos\theta=0cosθ=0, causing division by zero in tan⁡θ=sin⁡θcos⁡θ\tan\theta=\frac{\sin\theta}{\cos\theta}tanθ=cosθsinθ​.

B

Using periodicity and even symmetry, cos⁡(−13π3)=\cos\left(-\frac{13\pi}{3}\right)=cos(−313π​)= 12\boxed{\frac{1}{2}}21​​.

C

000

D

π\piπ radians
