What is (\sin(\frac{\pi}{2}+x)) equal to?(\sin(\frac{\pi}{2}+x)) किसके बराबर है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\cos x)(\cos x)
In the form (\frac{\pi}{2}+x), (\sin) changes to (\cos) and the sign remains positive. Hence the answer is (\cos x).(\frac{\pi}{2}+x) वाले रूप में (\sin) बदलकर (\cos) होता है और चिन्ह धनात्मक रहता है। इसलिए उत्तर (\cos x) है।
