Simplify csc θ(1−cos^2 θ)/sinθ cos θ to a single trigonometric function

topjm [15]

Answer:

<u><em></em></u> $\frac{cosec\alpha(1-cosx^{2} \alpha ) }{sin\alpha cos\alpha } = sec\alpha$ <u><em></em></u>

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the trigonometric function

$\frac{cosec\alpha(1-cosx^{2} \alpha ) }{sin\alpha cos\alpha }$

we know that sin²∝ + cos²∝ = 1

⇒ sin²∝ = 1- cos²∝

Now we have to simplify the given trigonometric function

= $\frac{cosec\alpha(sin^{2} \alpha ) }{sin\alpha cos\alpha }$

= $\frac{cosec\alpha(sin \alpha ) }{ cos\alpha }$

<u><em>Step(ii)</em></u>

we know that cosec∝ = 1/ sin∝

= $\frac{\frac{1}{sin\alpha } (sin \alpha ) }{ cos\alpha }$

After cancellation sine function, we get

= $\frac{1 }{ cos\alpha } = sec\alpha$

<u><em>Final answer:-</em></u>

<u><em></em></u> $\frac{cosec\alpha(1-cosx^{2} \alpha ) }{sin\alpha cos\alpha } = sec\alpha$ <u><em></em></u>
