What is the value of \(\cos^{-1}\left(\cos\frac{2\pi}{3}\right)\)?\(\cos^{-1}\left(\cos\frac{2\pi}{3}\right)\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(\frac{2\pi}{3}\)\(\frac{2\pi}{3}\)
The angle \(\frac{2\pi}{3}\) lies in the principal range \(\left[0,\pi\right]\) of \(\cos^{-1}x\). Hence the value is \(\frac{2\pi}{3}\).\(\frac{2\pi}{3}\) \(\cos^{-1}x\) के मुख्य परिसर \(\left[0,\pi\right]\) में है। इसलिए मान \(\frac{2\pi}{3}\) है।
