Question

Assertion :The value of cotangent function at the point $x=n\pi$ is not defined for integer values of n. Reason: The value of cotangent function at the point $x=n\pi$ becomes $\infty$.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

$\cot n\pi =\frac{\cos n\pi }{\sin n\pi }\approx \frac{1}{0}\approx \infty$ which is Not Defined Mathematically.

$\therefore$ Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
