Answer:

put value of cosec A + cot A and same cosecA - cot A

you got the Answer

Answer 2

Answer:

Answer: 1

Step-by-step explanation:

Let cosecA= x and cot A=y

Then

( cosecA+cotA) ( cosecA+cotA)

=(x+y)(x-y)

=x²-y² ( As we know that (x+y)(x-y)=x²-y²)

Putting back the values of x ant y

=cosec²x-cot²x

=1 ( As cosec²x-cot²x=1)
