The correct Answer is:
To find the value of \( \sin \theta \) given that \( \tan \theta = \sqrt{3} \), we can follow these steps: ### Step 1: Understand the relationship between tangent and sine We know that: \[ \tan \theta = \frac{\sin \theta}{\cos \theta} \] Given that \( \tan \theta = \sqrt{3} \), we can express this as: \[ \frac{\sin \theta}{\cos \theta} = \sqrt{3} \] ### Step 2: Identify the angle From trigonometric ratios, we know that: \[ \tan 60^\circ = \sqrt{3} \] Thus, we can conclude that: \[ \theta = 60^\circ \] ### Step 3: Find the value of \( \sin \theta \) Now that we have \( \theta = 60^\circ \), we can find \( \sin \theta \): \[ \sin 60^\circ = \frac{\sqrt{3}}{2} \] ### Final Answer Thus, the value of \( \sin \theta \) is: \[ \sin \theta = \frac{\sqrt{3}}{2} \] ---
