Where is (\cot x) undefined?(\cot x) कहाँ अपरिभाषित होता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\sin x=0)(\sin x=0)
(\cot x=\frac{\cos x}{\sin x}), so it is undefined when (\sin x=0). Always check the denominator carefully.(\cot x=\frac{\cos x}{\sin x}) है, इसलिए (\sin x=0) पर यह अपरिभाषित होता है। हर को हमेशा ध्यान से देखें।
