What is the principal value of \(tan^{-1}\left(\tan\frac{5\pi}{6}\right)\)?\(tan^{-1}\left(\tan\frac{5\pi}{6}\right)\) का मुख्य मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: -\(\frac{\pi}{6}\)-\(\frac{\pi}{6}\)
We have \(tan\frac{5\pi}{6}=-\frac{1}{\sqrt{3}}\). Thus \(tan^{-1}\left(-\frac{1}{\sqrt{3}}\right)=-\frac{\pi}{6}\).\(tan\frac{5\pi}{6}=-\frac{1}{\sqrt{3}}\) है। \(tan^{-1}\left(-\frac{1}{\sqrt{3}}\right)=-\frac{\pi}{6}\)।
