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

Prove each of the following identities : (i) sqrt((1+ sin theta)/(1- sin theta)) = ( sec theta + tan theta) (ii) sqrt((1- cos theta)/(1+ cos theta))= ("cosec" theta - cot theta) (iii) sqrt((1+ cos theta)/(1- cos theta))+ sqrt((1- cos theta)/(1+ cos theta)) = 2 "cosec" theta

Prove that sqrt(1+sin theta)/sqrt(1-sin theta)=sec theta + tan theta ,-(pi)/(2) lt theta lt (pi)/(2)

If 0<=theta<=pi and (sin0)/(2)=sqrt(1+sin theta)-sqrt(1-sin theta) then the possible value of tan theta, is -

If theta=240^(@) is the following statement correct? 2sin backslash(theta)/(2)=sqrt(1+sin theta)-sqrt(1-sin theta)

tan theta= A) (sqrt(1-sin^(2)theta))/(sin theta) , B) (1)/(sec theta) , C) (sin theta)/(sqrt(1-sin^(2)theta)) D) (1)/(sqrt(1+Cot^(2)theta)

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

cos theta=sqrt(1-sin theta)

cos theta=sqrt(1-sin theta)

If theta=60^@ then 1/2 sqrt(1+sin theta)+1/2sqrt(1-sin theta)=
