`sintheta=7/25` then `sqrt((1-cos theta)/(1+cos theta))=`

root(7)((1+cos theta)/(1-cos theta))+sqrt((1-cos theta)/(1+cos theta))=2cos ec theta

Find the value of sqrt((1+cos theta)/(1-cos theta))+sqrt((1-cos theta)/(1+cos theta))

Prove the following identities: sqrt((1-cos theta)/(1+cos theta))-cosec theta=cosec theta-sqrt((1+cos theta)/(1-cos theta))

Prove that sqrt((1+costheta)/(1-costheta))+sqrt((1-cos theta)/(1+cos theta))=2 " cosec"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

sqrt((1+ cos theta)/( 1- cos theta)) + sqrt((1- cos theta)/( 1 + cos theta )) ( 0 lt theta lt pi ) is

IF sintheta=sqrt3/2 , then cos theta =?

If sintheta_(1)+sintheta_(2)+sintheta_(3)=3, then cos theta_(1)+cos theta_(2)+cos theta_(3)=

If sintheta_(1)+sintheta_(2)+sintheta_(3)=3, then cos theta_(1)+cos theta_(2)+cos theta_(3)=

Assertion (A) : ((1+cos theta)/(sintheta))^(2)=(1+cos theta)/(1-cos theta) Reason (R ) : sin^(2)theta = cos^(2) theta-1
