Question

$\frac{\cos \theta }{\sec \theta }=\sin \theta \cos \theta$

• A. True
• B. False

Answer 1

The correct option is B False

$\frac{\cos \theta }{\text{sec}\theta }=\frac{\cos \theta }{\frac{1}{\cos \theta }}$

$=\cos \theta \times \cos \theta$

$={\cos }^2\theta$

So the given relation is $\text{False}$
