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

Prove the following identities, 0^(@) le theta le 90^(@) . (ii) (cos A)/(1+ sin A) + (1+sin A)/(cos A) = 2 sec A

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

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

Prove that (costheta)/(1-sin theta)+(1-sin theta)/(cos theta)=2sec theta .

Prove that (cos theta)/(1+sin theta)=(1-sin theta)/(cos theta)=sec theta-tan theta

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

1-(sin^(2)theta)/(1+cos theta)+(1+cos theta)/(sin theta)-(sin theta)/(1-cos theta) equals
