What is (\frac{\cos \theta}{\sec \theta}) equal to?(\frac{\cos \theta}{\sec \theta}) किसके बराबर होता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\cos^2 \theta)(\cos^2 \theta)
Since (\sec \theta=\frac{1}{\cos \theta}), (\frac{\cos \theta}{\sec \theta}=\cos^2 \theta). Writing the reciprocal makes simplification easy.(\sec \theta=\frac{1}{\cos \theta}) इसलिए (\frac{\cos \theta}{\sec \theta}=\cos^2 \theta) होता है। व्युत्क्रम लिखने से सरलीकरण आसान होता है।
