यदि \(\sin \theta=\frac{1}{2}\) और \(0<\theta<\pi\), तो \(\theta\) के मान कौन से हैं?
If \(\sin \theta=\frac{1}{2}\) and \(0<\theta<\pi\), what are the values of \(\theta\)?
Explanation opens after your attempt
A. \(\frac{\pi}{6},\frac{5\pi}{6}\)
Concept
The reference angle for \( \sin \theta=\frac{1}{2}\) is \( \frac{\pi}{6}\), and sine is positive in the first and second quadrants. In exams choose only answers in the given interval.
Why this answer is correct
The correct answer is A. \(\frac{\pi}{6},\frac{5\pi}{6}\). The reference angle for \( \sin \theta=\frac{1}{2}\) is \( \frac{\pi}{6}\), and sine is positive in the first and second quadrants. In exams choose only answers in the given interval.
Exam Tip
\(\sin \theta=\frac{1}{2}\) के reference angle \(\frac{\pi}{6}\) हैं और sine प्रथम व द्वितीय चतुर्थांश में धनात्मक है। परीक्षा में दिए interval में ही उत्तर चुनें।
