What is (\sin(\frac{3\pi}{2}+x)) equal to?(\sin(\frac{3\pi}{2}+x)) किसके बराबर है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: -(\cos x) / (-\cos x)-(\cos x) / (-\cos x)
In the form (\frac{3\pi}{2}+x), (\sin) changes to (\cos) with a negative sign. Hence the answer is (-\cos x).(\frac{3\pi}{2}+x) रूप में (\sin) बदलकर (\cos) होता है और चिन्ह ऋणात्मक होता है। इसलिए उत्तर (-\cos x) है।
