" 4."sec theta+tan theta=tan((pi)/(4)+(theta)/(2))

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

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

(sec theta-tan theta)/(sec theta+tan theta)=cos^(2)((pi)/(4)+(theta)/(2))

If theta in((pi)/(4),(pi)/(2)) and f(theta)=sec 2theta- tan 2theta , then f((pi)/(4)-theta)=

sqrt((1-sin theta)/(1+sin theta))={sec theta-tan theta, if -(pi)/(2)

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

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

{(tan((pi)/(4)+theta)+tan((pi)/(4)-theta))/(tan((pi)/(4)+theta)-tan((pi)/( 4)-theta)))

If tan((pi)/(4)+theta)+tan((pi)/(4)-theta)=a, then tan^(2)((pi)/(4)+theta)+tan^(2)((pi)/(4)-theta)=
