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

(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)

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

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

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)

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