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
