सिद्ध कीजिए की : ` cosec 2A + cot2A =cotA `

cosec A -2 cot 2A cos A=

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

cosec A- 2cot 2A cos A=

csc2A+cot2A=?

( 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 .

Prove the following identities : cosec^(4) A - cosec^(2) A = cot^(4) A + cot^(2) A

tan A + cot A = 2 cosec 2A

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

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

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