If theta=60^@ ,then (frac(1+tan^2theta)(2tantheta)) is equal to…….

What is (2 tan theta)/(1+tan^2theta) equals to ?

If tan theta + (1)/(tan theta) = 2, then tan^2 theta + (1)/(tan^2 theta) is equal to

(tan^(2)(2 theta)-tan^(2)theta)/(1-tan^(2)(2 theta)tan^(2)theta) is equal to-

If (theta) lies in III quadrant and sin theta=(-4)/(5) , then the value of tan^(2)((theta)/(2)) is equal to

If tan2 theta*tan theta=1, then theta=

If tan 3 theta + tan theta =2 tan 2 theta , then theta is equal to (n in Z)
