`tan(pi/4+theta)-tan(pi/4-theta)=2tan2theta`

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

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

Prove that: tan(pi/4+theta)+tan(pi/4-theta)=2sec2theta .

If tan(pi/4+theta)+tan(pi/4-theta)=a, then tan^(2)(pi/4+theta)+tan^(2)(pi/4-theta)=(a)a^(2)+1 (b) a^(2)+2(c)a^(2)-2(d) none of these

Match the following . {:((1) tan(pi/4+theta)-tan(pi/4-theta)=,(a) 1),((b)tan(pi/4+theta)+cot(pi/4+theta)=,(b)4sec^(2)2theta),((c)tan(pi/4+theta).tan(pi/4-theta)=,(c)2sec2theta),((d)cosec^(2)(pi/4+theta)cosec^(2)(pi/4-theta)=,(d)2tan2theta):}

IF y=(tan(pi/4+theta)+tan(pi/4-theta))/(tan(pi/4+theta)-tan(pi/4-theta)) then find y.

If tan((pi)/(4)+theta)+tan((pi)/(4)-theta)=a then tan^(3)((pi)/(4)+theta)+tan^(3)((pi)/(4)-theta)=

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