The value of is
Note: Since all the options involve the trigonometric ratios cosec θ and cot θ, so we divide the whole term (numerator as well as denominator) by sin θ.
To find:
Consider
Dividing numerator and denominator by sin θ, we get
Rationalizing the term by multiplying it by ,
Now, as 1 + cot2 θ = cosec2 θ
⇒ cosec2 θ – cot2 θ = 1
