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

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

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

If (pi)/(2)

If pi/2 lt theta lt pi then sqrt((1-sin theta)/(1+sin theta))+sqrt((1+sin theta)/(1-sin theta))=

If theta lies in the second quadrant. Then the value of sqrt((1-sin theta)/(1+sin theta))+sqrt((1+sin theta)/(1-sin theta)) is equal to :
