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

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

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

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

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):}

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

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

If tan theta = 3/4 and theta is not in the first quadrant then (sin (pi//2 + theta)-cot(pi-theta))/(tan(3 pi//2 - theta)-cos (3pi//2+theta))=

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