Answer:
1
- Given Cosec thetha + cot thetha = x
- y = Cosec thetha - cot thetha
- We know that Sin^2 thetha + Cos^2 thetha = 1 equation 1
- So multiplying x and y we get cosec^2 thetha - cot^2 thetha
- Divide equation 1 with Sin^2 thetha then we will get 1 + Cot^2 thetha = Cosec^2 thetha
- So finally the answer is 1
