    Question

    If then what is the value of cosecθ ?

    A.

    13/12

    B.

    3/2

    C.

    11/12

    D.

    9/13

    Correct option is A

    Given: 
    cosecθ+cotθ=32\cosec \theta + \cot \theta = \frac{3}{2} 
    Concept Used: 
    1+cot2θ=cosec2θ cosec2θcot2θ=1 (cosecθ+cotθ)(cosecθcotθ)=1 cosecθ+cotθ=1cosecθcotθ1 + \cot^2 \theta = \cosec^2 \theta \\ \implies \cosec^2 \theta - \cot^2 \theta = 1 \\ \implies (\cosec\theta + \cot \theta) (\cosec\theta -\cot \theta) = 1 \\ \implies \cosec\theta + \cot \theta = \frac{1}{\cosec\theta -\cot \theta}
