cot^(2)A((sec A-1)/(1+sin A))+sec^(2)A((sin A-1)/(1+sec A))=0

Prove the following identities: (sin A+sec A)^(2)+(cos A+csc A)^(2)=(1+sec A csc A)^(2)cot^(2)A((sec A-1)/(1+sin A))+sec^(2)A((sin A-1)/(1+sec A))=0

(cot^(2)A(sec A-1))/(1+sin A)=sec^(2)A((1-sin A)/(1+sec A))

Prove the following identities : cot^(2) A ((sec A - 1)/(1 + sin A)) + sec ^(2) A ((sin A -1)/ (1 + sec A)) = 0

((sin 2A)/(sec A -1))((sec 2A)/(sec 2A+1))=

(1+sec A)/(sec A)=(sin^(2)A)/(1-cos A)

sqrt((1+sin A)/(1-sin A))=sec A+tan A

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

sqrt((1-sin A)/(1+sin A))+sqrt((1+sin A)/(1-sin A))=2sec A

((sin2A)/(secA-1))((sec2A)/(sec2A+1))=
