Card 0 of 1

Question

$\textup{Which of the following expressions is equal to }\frac{\tan \theta }{\sec \theta }:\textup{?}$

Answer

$\textup{Use identities to solve: }\tan\theta=\frac{\sin \theta }{\cos \theta }:::::\sec\theta=\frac{1}{\cos \theta }$

$\frac{\tan \theta }{\sec \theta }=\frac{\sin \theta }{\cos \theta }\times\frac{\cos \theta }{1}=\sin\theta$
