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

Prove that (cos A)/(1+sin A)+(1+sin A)/(cos A)=2sec A

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

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

Prove the following identities: (cos A)/(1-sin A)+(sin A)/(1-cos A)+1=(sin A cos A)/((1-sin A)(1-cos A))((1+cot A+tan A)(sin A-cos A)/(sec^(3)A-cos ec^(3)A)=sin^(2)A cos^(2)A

To prove '(cos A / 1 + sin A) + (1 + sin A / cos A) = 2sec A

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

(sec A+tan A)(1-sin A)=sec A(b)sin A(c)cos ecA(d)cos A

(cos theta)/(1+sin theta)+(1+sin theta)/(cos theta)=2sec theta

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