फलन \(\cosec x\) किसका व्युत्क्रम है?
The function \(\cosec x\) is the reciprocal of which function?
Explanation opens after your attempt
B. \(\sin x\)
Simple Explanation
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। / 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 \(\tan\)–\(\cot\).
