At standard angles, sin⁡30∘=\sin 30^\circ=sin30∘= [...]\text{[...]}[...], cos⁡45∘=\cos 45^\circ=cos45∘= 22\frac{\sqrt2}{2}22​​, and tan⁡60∘=\tan 60^\circ=tan60∘= 3\sqrt33​.

A

At standard angles, sin⁡30∘=\sin 30^\circ=sin30∘= 12\boxed{\frac12}21​​, cos⁡45∘=\cos 45^\circ=cos45∘= 22\frac{\sqrt2}{2}22​​, and tan⁡60∘=\tan 60^\circ=tan60∘= 3\sqrt33​.

B

θ=90∘, 210∘, 330∘\theta=90^\circ,\ 210^\circ,\ 330^\circθ=90∘, 210∘, 330∘.

C

Each root can produce a different set of angle solutions.

D

At standard angles, sin⁡30∘=\sin 30^\circ=sin30∘= 12\frac1221​, cos⁡45∘=\cos 45^\circ=cos45∘= 22\frac{\sqrt2}{2}22​​, and tan⁡60∘=\tan 60^\circ=tan60∘= 3\boxed{\sqrt3}3​​.
