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

cosec A -2 cot 2A cos A=

cosec A- 2cot 2A cos A=

"cosec"(3 - 2x) cot (3 - 2x)

int cot^3x cosec^2 xdx

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

tan A + cot A = 2 cosec 2A

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

Prove that: ("cosec" theta + cot theta)/("cosec" theta - cot theta) = ("cosec" theta + cot theta )^(2) = 1 + 2 cot^(2) theta + 2 "cosec" theta cot theta .

( 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 .
