Convert (120^\circ) into radians.(120^\circ) को रेडियन में बदलें।
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(\frac{2\pi}{3}\)\(\frac{2\pi}{3}\)
To convert degrees to radians, multiply the angle by \(\frac{\pi}{180}\). Thus, \(120^\circ=120\times\frac{\pi}{180}=\frac{2\pi}{3}\) radians. Note that \(\frac{5\pi}{6}\) radians equals \(150^\circ\), so it is not correct here. Exam tip: Remember that \(180^\circ=\pi\) radians.डिग्री को रेडियन में बदलने के लिए कोण को \(\frac{\pi}{180}\) से गुणा करते हैं। अतः \(120^\circ=120\times\frac{\pi}{180}=\frac{2\pi}{3}\) रेडियन। \(\frac{5\pi}{6}\) रेडियन \(150^\circ\) के बराबर होता है, इसलिए वह सही नहीं है। परीक्षा टिप: \(180^\circ=\pi\) रेडियन का संबंध याद रखें।
