Q4 of 153 Page 7

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
