Given that $\sin\theta=\frac{1}{2}$sinθ=12, we want to find the value of $\cos\theta$cosθ.

First, find the value of $\theta$θ.

Hence, find the exact value of $\cos30^\circ$cos30°.

Given that $\sin\theta=\frac{1}{2}$sinθ=12, we wish to find $\tan\theta$tanθ.

Given that $\cos\theta=\frac{\sqrt{3}}{2}$cosθ=√32, we want to find the value of $\sin\theta$sinθ.

Given that $\cos\theta=\frac{1}{2}$cosθ=12.
