\( \frac{5\pi}{9} \) रेडियन किस चतुर्थांश में है?
In which quadrant is \( \frac{5\pi}{9} \) radians?
Explanation opens after your attempt
Correct Answer
B. द्वितीय चतुर्थांशSecond quadrant
Concept
\( \frac{\pi}{2}<\frac{5\pi}{9}<\pi \), so it lies in the second quadrant. Remember the interval between \( \frac{\pi}{2} \) and \( \pi \).
Why this answer is correct
The correct answer is B. द्वितीय चतुर्थांश / Second quadrant. \( \frac{\pi}{2}<\frac{5\pi}{9}<\pi \), so it lies in the second quadrant. Remember the interval between \( \frac{\pi}{2} \) and \( \pi \).
Exam Tip
\( \frac{\pi}{2}<\frac{5\pi}{9}<\pi \) है इसलिए यह द्वितीय चतुर्थांश में है। \( \frac{\pi}{2} \) और \( \pi \) की सीमा याद रखें।
