Answer :
1/x
Step-by-step explanation:
cosec A + cot A = x
( cosec A - cot A )^2 = 1
(cosec A + cot A ) ( cosec A - cot A ) =1
x ( cosec A - cot A ) = 1
( cosec A - cot A ) = 1/x

Step-by-step explanation:
By Trigonometric Identity,
Cosec²A - Cot²A = 1
So,
Cosec²A - Cot²A = 1
=>(cosecA + cot A)(cosecA - cotA) = 1
[a² - b² = (a + b)(a - b)]
Putting the value of (cosecA - cotA) we get,
=>x(cosecA - cotA) = 1
[ coseccA + cotA = x (given)]
=> cosecA - cotA = 1/x
