`cosec2A + cot2A = cotA`

" cosec 2x + cot 2x = cot x "

Prove the following identities : ((cosec A - cot A)^(2) + 1)/(sec A (cosec A - cot A)) = 2 cot A

cosec A -2 cot 2A cos A=

cosec A- 2cot 2A cos A=

( cos A - sin A + 1 ) / ( cos A + sin A - 1 ) = cosec A + cot A cosec A + cot A , = using the identity cosec ^ 2 A = 1 + cot^ 2 A .

The value of (cosec 2A - cot 2A) is-

Prove that : cosec A- cot A =(1)/(cosecA+cotA)

Prove that : cosec A- cot A =(1)/(cosecA+cotA)

Prove that: cot2A + tanA= cotA - cot 2A
