cot theta-tan theta-2tan2 theta-4tan4 theta=

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

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

If tan theta=(pi)/(7) then find the value of (tan theta.tan2 theta+tan2 theta tan4 theta+tan4 theta*tan theta) is....

Show that: If theta=(2 pi)/(7), prove that tan theta tan2 theta+tan2 theta tan4 theta+tan4 theta tan 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

(cot theta)/(cot theta-cot3 theta)+(tan theta)/(tan theta-tan3 theta) is equal to

(cot theta)/(cot theta-cot3 theta)+(tan theta)/(tan theta-tan3 theta) is equal to:

If tan theta+tan4 theta+tan7 theta=tan theta tan4 theta tan7 theta, then theta is equal to
