What is the principal angle between (0) and (2\pi) for (-\frac{101\pi}{18})?कोण (-\frac{101\pi}{18}) का (0) से (2\pi) के बीच मुख्य कोण क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\frac{7\pi}{18})(\frac{7\pi}{18})
(-\frac{101\pi}{18}+6\pi=\frac{7\pi}{18}). In exams, writing (6\pi) as (\frac{108\pi}{18}) makes addition easy.(-\frac{101\pi}{18}+6\pi=\frac{7\pi}{18})। परीक्षा में (6\pi) को (\frac{108\pi}{18}) लिखकर जोड़ना आसान होता है।
