(1)/(sin A+cos A+1)+(1)/(sin A+cos A-1)=sec A+cosec A

(1) / (sin A + cos A + 1) + (1) / (sin A + cos A-1) = sec A + csc A

Prove that (sin A)/(1 + cos A) + (sin A)/(1 - cos A) = 2 cosec A.

Prove that : (sin A - cos A) (1 + tan A + cot A) = (sec A)/ (cosec^(2) A) - (cosec A)/ (sec^(2) A)

(cos A)/(1+sin A)+(sin A)/(cos A)=sec A

(1+tan A)/(sin A)+(1+cot A)/(cos A)=2(sec A+cosec A)

sin A (1 + tan A) + cos A (1 + cot A) = sec A + cosec A .

Prove that : sin A (1 + tan A) + cos A (1 + cot A) = sec A + cosec 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 .

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

sin A(1+tan A)+cos A(1+cot A)=sec A+cosec A
