\(\tan x=\frac{\sin x}{\cos x}\), so it is undefined when \(\cos x=0\). A fraction is not defined when the denominator is zero.
Step 2
Why this answer is correct
The correct answer is A. \(\cos x=0\). \(\tan x=\frac{\sin x}{\cos x}\), so it is undefined when \(\cos x=0\). A fraction is not defined when the denominator is zero.
Step 3
Exam Tip
\(\tan x=\frac{\sin x}{\cos x}\) है, इसलिए \(\cos x=0\) पर यह अपरिभाषित होता है। हर शून्य होने पर भिन्न परिभाषित नहीं रहती।
