The function (\cosec x) is the reciprocal of which function?फलन (\cosec x) किसका व्युत्क्रम है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(\sin x\)\(\sin x\)
The correct answer is \(\sin x\), because \(\cosec x=\frac{1}{\sin x}\). Thus, \(\cosec x\) is the multiplicative reciprocal of \(\sin x\). \(\sec x\) is the reciprocal of \(\cos x\), so it is not correct here. Exam tip: Remember the reciprocal pairs \(\sin\)–\(\cosec\), \(\cos\)–\(\sec\), and \(\tan\)–\(\cot\).सही उत्तर \(\sin x\) है, क्योंकि \(\cosec x=\frac{1}{\sin x}\) होता है। इसलिए \(\cosec x\), \(\sin x\) का गुणात्मक व्युत्क्रम है। \(\sec x\), \(\cos x\) का व्युत्क्रम होता है, इसलिए वह विकल्प सही नहीं है। परीक्षा टिप: \(\sin\)–\(\cosec\), \(\cos\)–\(\sec\) और \(\tan\)–\(\cot\) व्युत्क्रम युग्म याद रखें।
