" Prove that "tan((pi)/(4)+(theta)/(2))+tan((pi)/(4)-(theta)/(2))=2sec theta

Prove that tan ((pi )/(4) + (theta )/(2) ) + tan ((pi )/(4) - (theta)/(2)) = 2 sec theta.

Prove that: tan((pi)/(4)+theta)+tan((pi)/(4)-theta)=2sec2 theta

Prove that tan((pi)/(4)+theta)-tan((pi)/(4)-theta)=2tan2theta .

Prove that tan ((pi)/(4) + theta)- tan ((pi)/(4) - theta) = 2 tan 2 theta .

Prove that : tan((pi)/(4)+theta)+tan((pi)/(4)-theta)=2sec2 theta

tan((pi)/(4)+theta)-tan((pi)/(4)-theta)=2tan2 theta

(1-tan^(2)((pi)/(4)-theta))/(1+tan^(2)((pi)/(4)-theta))=sin2 theta

tan ((pi)/(4) + (theta)/(2)) + tan ((pi)/(4) -(theta)/(2)) is equal to ............... A) sec theta B) 2 sec theta C) sec "" (theta)/(2) D) -2 sec theta

If tan((pi)/(4)+theta)+tan((pi)/(4)-theta)=4 then theta=

Prove that, tan (pi/4 + theta) + tan (pi/4 - theta) = 2 sec 2 theta
