Which value is not possible from the range of (\cos^{-1}x)?(\cos^{-1}x) की सीमा से कौन सा मान संभव नहीं है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-\frac{\pi}{3})(-\frac{\pi}{3})
The range of (\cos^{-1}x) is ([0,\pi]), so a negative value is not possible. In such questions check only the output range.(\cos^{-1}x) की सीमा ([0,\pi]) है इसलिए ऋणात्मक मान संभव नहीं है। ऐसे प्रश्नों में केवल आउटपुट रेंज देखें।
