(1+sin A-cos A)/(y+sin A+cos A)

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

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

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

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

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

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