Where is (\tan x) undefined?(\tan x) कहाँ अपरिभाषित होता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\cos x=0)(\cos x=0)
(\tan x=\frac{\sin x}{\cos x}), so it is undefined when (\cos x=0). A fraction is not defined when the denominator is zero.(\tan x=\frac{\sin x}{\cos x}) है, इसलिए (\cos x=0) पर यह अपरिभाषित होता है। हर शून्य होने पर भिन्न परिभाषित नहीं रहती।
