" 4."(sqrt(1+sin theta))/(1-sin theta)+sqrt((1-sin theta)/(1+sin theta))=?

sqrt((1+sin theta)/(1-sin theta))+sqrt((1-sin 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

cos theta=sqrt(1-sin theta)

cos theta=sqrt(1-sin theta)

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

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

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 :

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 :
