cot theta-tan theta=2

Given that cot theta-tan theta=2cot2 theta , cot theta+tan theta=2cosec2 theta and cot theta-cot2 theta=cosec2 theta, Tan alpha + 2Tan2 alpha+4Tan4 alpha+.....2^(n)Tan2^(n)alpha=cot alpha-1024cot1024 alpha Then n= a) 10 b) 9 c) 11 d) 8

Prove that, (cot theta - tan theta)/(1-2 sin ^(2) theta) = sec theta "cosec" theta

The value of cot theta-tantheta-2tan2theta-4tan4theta-8cot8theta, is

The value of cot theta-tantheta-2tan2theta-4tan4theta-8cot8theta, is

(tan theta)/(1+cot theta)=(tan theta-1)/(2-cos ec^(2)theta)

(tan theta+cot theta)/(tan theta-cot theta)=2,(0<=theta<=90^(@)) then the value of sin theta is

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

Solve 4cot2theta=cot^2theta-tan^2theta

Solve 4cot2theta=cot^2theta-tan^2theta
