`cosec A + cot A = "cot " (A)/(2)`

cosec A -2 cot 2A cos A=

cosec A- 2cot 2A cos A=

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

tan A + cot A = 2 cosec 2A

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

Prove that : (sec A - tan A)/ (cosec A + cot A) = (cosec A - cot A)/ (sec A + tan A)

csc2A+cot2A=?

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

Prove the following : (cot A - cos A)/(cot A + cos A) = (cosec A -1)/(cosec A + 1) .
