Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: -(\sin x) / (-\sin x)-(\sin x) / (-\sin x)
(\frac{3\pi}{2}-x) is related to the third quadrant. (\cos) changes to (\sin) with a negative sign.(\frac{3\pi}{2}-x) तीसरे चतुर्थांश से जुड़ा है। (\cos) बदलकर (\sin) होता है और चिन्ह ऋणात्मक रहता है।
