यदि \( \theta= -\frac{13\pi}{6} \) है तो उसका संदर्भ कोण क्या है?
If \( \theta= -\frac{13\pi}{6} \), what is its reference angle?
Explanation opens after your attempt
Correct Answer
A. \( \frac{\pi}{6} \)
Concept
\( -\frac{13\pi}{6}+\frac{24\pi}{6}=\frac{11\pi}{6} \), and the reference angle is \( \frac{\pi}{6} \). First bring the negative angle into (0) to \(2\pi\).
Why this answer is correct
The correct answer is A. \( \frac{\pi}{6} \). \( -\frac{13\pi}{6}+\frac{24\pi}{6}=\frac{11\pi}{6} \), and the reference angle is \( \frac{\pi}{6} \). First bring the negative angle into (0) to \(2\pi\).
Exam Tip
\( -\frac{13\pi}{6}+\frac{24\pi}{6}=\frac{11\pi}{6} \) और संदर्भ कोण \( \frac{\pi}{6} \) है। ऋणात्मक कोण को पहले (0) से \(2\pi\) में लाएं।
