What is the value of \(\cos^{-1}\left(\cos\frac{5\pi}{6}\right)\)?\(\cos^{-1}\left(\cos\frac{5\pi}{6}\right)\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(\frac{5\pi}{6}\)\(\frac{5\pi}{6}\)
The angle \(\frac{5\pi}{6}\) lies in the principal range \(\left[0,\pi\right]\). Hence \(cos^{-1}\left(cos\frac{5\pi}{6}\right)=\frac{5\pi}{6}\).\(\frac{5\pi}{6}\) मुख्य परिसर \(\left[0,\pi\right]\) में है। इसलिए \(cos^{-1}\left(\cos\frac{5\pi}{6}\right)=\frac{5\pi}{6}\)।
