Prove that:
`sqrt(1-sintheta)/sqrt(1+sintheta) = sec theta - tan theta`

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

Prove the identitie (cos theta)/(1+ sin theta) = sec theta - tan theta

Prove that (cos theta-sintheta)/(cos theta+sintheta)=sec 2 theta-tan 2theta .

Prove that following identities sqrt((1+sintheta)/(1-sintheta))=sectheta+tantheta

sqrt((1+sintheta)/(1-sintheta))=sectheta+x. Then x is:

Prove that (1+sintheta)/costheta+costheta/(1+sintheta)=2sectheta

Prove: sec theta + tan theta = 1/(sec theta - tan theta)

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

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