What is the principal value of \(cot^{-1}\left(-\sqrt{3}\right)\)?\(cot^{-1}\left(-\sqrt{3}\right)\) का मुख्य मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(\frac{5\pi}{6}\)\(\frac{5\pi}{6}\)
We have \(cot\frac{5\pi}{6}=-\sqrt{3}\). The principal value of \(cot^{-1}x\) must be taken in \(\left(0,\pi\right)\).\(cot\frac{5\pi}{6}=-\sqrt{3}\) होता है। \(cot^{-1}x\) का मुख्य मान \(\left(0,\pi\right)\) में लेना चाहिए।
