What is the principal value of \(tan^{-1}\left(\tan\frac{3\pi}{4}\right)\)?\(tan^{-1}\left(\tan\frac{3\pi}{4}\right)\) का मुख्य मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: -\(\frac{\pi}{4}\)-\(\frac{\pi}{4}\)
We have \(tan\frac{3\pi}{4}=-1\) and \(tan^{-1}\left(-1\right)=-\frac{\pi}{4}\). Remember the principal range \(\left(-\frac{\pi}{2},\frac{\pi}{2}\right)\).\(tan\frac{3\pi}{4}=-1\) है और \(tan^{-1}\left(-1\right)=-\frac{\pi}{4}\)। मुख्य परिसर \(\left(-\frac{\pi}{2},\frac{\pi}{2}\right)\) याद रखें।
