    Step-by-step explanation:

    Given : cosec x – cot x =  

    3

    1

    ​  

     ………. (1)

    We know, cosec  

    2

     x−cot  

    2

     x=1  

    ⟹ (cosec x – cot x)(cosec x + cot x) =1

    ⟹  

    3

    1

    ​  

     (cosec x + cot x) =1

    ⟹ cosec x + cot x =3 ………… (2)

    Solving (1) and (2) we get,

    cosec x =  

    6

    10  =  3
    5 and cot x =  3
    4

    ​∴ sinx=  53cosec x

    cot x  = 54

    ​∴ cosx=  54

    ​∴ cos  

    2  x−sin  2  x=(  25
    16 )−(  25
    9 )= 25
    7
