`cot 2 theta + tan theta =`

Prove the following: cot^2 theta - tan^2 theta = cosec^2 theta - sec^2 theta

Prove the following : cot^2 theta - tan^2 theta = cosec^2 theta -sec^2 theta

cot2 theta+tan theta

If 180^(@) lt theta lt 270^(@) and sin theta = -5//13 then 5 cot^(2) theta + 12 tan theta + 13 "cosec" theta =

The value of (sec^2theta + 2 tan theta cot theta - tan^2 theta ) is

tan theta + 2 tan 2 theta + 4 tan 4 theta + 8 cot 8 theta = cot theta.

tan theta + 2 tan 2 theta + 4 tan 4 theta + 8 cot 8 theta = cot theta.
