Answer 1

I thin the answer is A

Answer 2

The expression simplifies to:

=
`(\tan\theta)/(\sin ^2 \theta+\cos ^2 \theta)=\tan\theta}`

Explanation:

Given trigonometric expression:

`(\tan\theta)/(\sin ^2 \theta+\cos ^2 \theta)`

Using identity :

`\sin ^2 \theta+\cos ^2 \theta=1`

`(\tan\theta)/(\sin ^2 \theta+\cos ^2 \theta)`

`=(\tan\theta)/(1)`

The expression simplifies to:

=
`(\tan\theta)/(\sin ^2 \theta+\cos ^2 \theta)=\tan\theta}`
