Cotangent Value
1. The problem states that $\cot \theta = \frac{\sqrt{3}}{2}$. We need to find $\theta$ or related trigonometric values.
2. Recall that $\cot \theta = \frac{\cos \theta}{\sin \theta}$. So, we have:
$$\frac{\cos \theta}{\sin \theta} = \frac{\sqrt{3}}{2}$$
3. This implies:
$$\cos \theta = \frac{\sqrt{3}}{2} \sin \theta$$
4. Using the Pythagorean identity $\sin^2 \theta + \cos^2 \theta = 1$, substitute $\cos \theta$:
$$\sin^2 \theta + \left(\frac{\sqrt{3}}{2} \sin \theta\right)^2 = 1$$
5. Simplify:
$$\sin^2 \theta + \frac{3}{4} \sin^2 \theta = 1$$
$$\left(1 + \frac{3}{4}\right) \sin^2 \theta = 1$$
$$\frac{7}{4} \sin^2 \theta = 1$$
6. Solve for $\sin^2 \theta$:
$$\sin^2 \theta = \frac{4}{7}$$
7. Take the square root:
$$\sin \theta = \pm \frac{2}{\sqrt{7}}$$
8. Find $\cos \theta$ using step 3:
$$\cos \theta = \frac{\sqrt{3}}{2} \times \pm \frac{2}{\sqrt{7}} = \pm \frac{\sqrt{3}}{\sqrt{7}}$$
9. Therefore, the possible values for $\sin \theta$ and $\cos \theta$ are:
$$\sin \theta = \pm \frac{2}{\sqrt{7}}, \quad \cos \theta = \pm \frac{\sqrt{3}}{\sqrt{7}}$$
10. The angle $\theta$ can be found by:
$$\theta = \cot^{-1} \left(\frac{\sqrt{3}}{2}\right)$$
Final answer:
$$\sin \theta = \pm \frac{2}{\sqrt{7}}, \quad \cos \theta = \pm \frac{\sqrt{3}}{\sqrt{7}}, \quad \theta = \cot^{-1} \left(\frac{\sqrt{3}}{2}\right)$$
