If (0<a<1), which statement about (\sin^{-1}a) and (\cos^{-1}a) is always true?यदि (0<a<1), तो (\sin^{-1}a) और (\cos^{-1}a) के बारे में कौन-सा कथन हमेशा सही है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Their sum is (\frac{\pi}{2})उनका योग (\frac{\pi}{2}) है
For every (a\in[-1,1]), (\sin^{-1}a+\cos^{-1}a=\frac{\pi}{2}). They are equal only at (a=\frac{1}{\sqrt{2}}).हर (a\in[-1,1]) के लिए (\sin^{-1}a+\cos^{-1}a=\frac{\pi}{2})। बराबर केवल (a=\frac{1}{\sqrt{2}}) पर होते हैं।
