<u><em></em></u>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the trigonometric function

we know that sin²∝ + cos²∝ = 1
⇒ sin²∝ = 1- cos²∝
Now we have to simplify the given trigonometric function
= 
= 
<u><em>Step(ii)</em></u>
we know that cosec∝ = 1/ sin∝
= 
After cancellation sine function, we get
=
