Question

Which expression is equivalent to (sin 2θ)(sec2θ)? 2sin θ sin θ tan θ 2tan θ

Answer 1

Answer:

Explanation:

Here, we want to get the expression that is equivalent to the given expression

We have this as follows:

$\begin{gathered} \text{ sec 2}\theta=\text{ }\frac{\sec^2\theta}{2-\sec^2\theta} \\ \\ \sin 2\theta\text{ = 2sin}\theta\cos \theta \end{gathered}$

Now, we can rewrite the overall expression as:

$undefined$
