" 2.Prove that: "sqrt((1+sin theta)/(1-sin theta))+sqrt((1-sin theta)/(1+sin theta))=2sec theta

Prove that sqrt((1-sin theta)/(1+sin theta))+sqrt((1+sin theta)/(1-sin theta))=-2/cos theta ,where pi/2ltthetaltpi .

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

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

Prove that tan theta+sqrt((1-sintheta)/(1+sin theta))=sec theta.

Prove that (1+sin theta)/(1-sin theta)-(1-sin theta)/(1+sin theta)=4sec theta tan theta

If (pi)/(2)

If pi/2 < theta < pi, then sqrt((1- sin theta)/(1+ sin theta))+sqrt((1+ sin theta)/(1- sin theta)) is equal to

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

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