`(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

Prove the following identity,where the angles invorved are acute angles for which the expressions are defined.(ii) (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

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

(1)/(sec^(4)alpha)+(1)/(cos ec^(4)alpha)+(2)/(sec^(2)alpha+cos ec^(2)alpha)=? and (cos A)/(1+sin A)+(1+sin A)/(cos A)=?

(1)/(sec^(4)alpha)+(1)/(cos ec^(4)alpha)+(2)/(sec^(2)alpha+cos ec^(2)alpha)=? and (cos A)/(1+sin A)+(1+sin A)/(cos A)=?

(sin2A) / (sin A) - (cos2A) / (cos A) = sec A

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