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

(ii)Find the value of tan(pi/4+theta)tan(pi/4-theta)

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 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

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

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

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

If tan(pi/4+theta)+tan(pi/4-theta)=lambda sec2 theta, them 3(b)4(c)1 ( textrmd ) 2

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

tan(pi/4+theta/2)+tan(pi/4-theta/2) is equal to

tan(pi/4+theta)tan((3pi)/4+theta) is equal to
