Evaluate: sqrt((1-sin theta)/(1+sin theta)) .

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

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

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

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

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

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

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

If (pi)/(2)
