cot theta-tan theta=2cot2 theta

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=2cot 2 theta .

Prove that cot theta-tan theta=2cot 2 theta .

Prove that cot theta-tan theta=2cot 2 theta .

cot2 theta+tan theta

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

Prove that, cot theta - tan theta = 2cot 2 theta

Prove that (tan theta+cot theta+1)(tan theta+cot theta-1)=sec^2 theta+cot^2 theta

prove that cot theta.cot2 theta+cot2 theta*cot3 theta+2=cot theta(cot theta-cot3 theta)

Prove that: cot theta cot2 theta+cot2 theta cot3 theta+2=cot theta(cot theta-cot3 theta)
