What is the principal positive angle between (0) and (2\pi) for (-\frac{31\pi}{6})?कोण (-\frac{31\pi}{6}) का (0) से (2\pi) के बीच मुख्य धनात्मक कोण क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\frac{5\pi}{6})(\frac{5\pi}{6})
Adding (6\pi) to (-\frac{31\pi}{6}) gives (\frac{5\pi}{6}). In exams, add multiples of (2\pi) to negative angles.(-\frac{31\pi}{6}) में (6\pi) जोड़ने पर (\frac{5\pi}{6}) मिलता है। परीक्षा में ऋणात्मक कोण में (2\pi) के गुणज जोड़ें।
