At which values is (\tan x) not defined?(\tan x) किस अंतराल में परिभाषित नहीं है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x=\frac{\pi}{2}+n\pi)(x=\frac{\pi}{2}+n\pi)
Since (\tan x=\frac{\sin x}{\cos x}), it is undefined when (\cos x=0). Thus (x=\frac{\pi}{2}+n\pi).(\tan x=\frac{\sin x}{\cos x}) है, इसलिए (\cos x=0) पर यह अपरिभाषित होता है। अतः (x=\frac{\pi}{2}+n\pi)।
