`tan^(-1)(tansqrt(1-theta))=sqrt(1-theta)` when

tan(2tan^(-1)sqrt((1+cos theta)/(1-cos theta)))+tan theta=0

tan ( 2 tan ^(-1)sqrt((1+cos theta)/(1-cos theta)))+ tan theta =0

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

prove that , tan(2tan ^(-1) sqrt((1+cos theta )/(1- cos theta )))+tan theta =0

(tan3theta-1)/(tan3theta+1)=sqrt(3) , then the general value of theta is

(tan3 theta-1)/(tan3 theta+1)=sqrt(3), then the general value of theta

(2cos^(2)theta-1)((1+tan theta)/(1-tan theta)+(1-tan theta)/(1+tan theta))=?

Prove that: sqrt((1-sintheta)/(1+sintheta))= sec theta- tan theta when (-pi/2) < theta < pi/2 and -sec theta+tan theta when pi/2< theta< (3pi)/2

Prove that: sqrt((1-sintheta)/(1+sintheta))= sec theta- tan theta when (-pi/2) < theta < pi/2 and -sec theta+tan theta when pi/2< theta< (3pi)/2

then the value of the expression E=(sqrt(1+tan^(2)theta))/(tan theta)-(sqrt(1+cot^(2)theta))/(cot theta) is equal to
