What is (\frac{1}{1+\tan^2 \theta}) equal to?(\frac{1}{1+\tan^2 \theta}) किसके बराबर होता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\cos^2 \theta)(\cos^2 \theta)
(\1+\tan^2 \theta=\sec^2 \theta) and (\frac{1}{\sec^2 \theta}=\cos^2 \theta). Be careful while taking reciprocals.(\1+\tan^2 \theta=\sec^2 \theta) और (\frac{1}{\sec^2 \theta}=\cos^2 \theta) होता है। व्युत्क्रम लेते समय सावधानी रखें।
