Prove that :` cosec theta + cosec 2 theta + cosec 2^2 theta +...........+cosec2^(n-1) theta= cot(theta/2)-cot 2^(n-1)theta`

cosec^2 theta - cot^2 theta = 1 +…..

cosec^(2)theta=1+cot^(2)theta

Prove that 1+cot^(2) theta = cosec^(2) theta

Prove that 1+cot^(2) theta = cosec^(2) theta

show that 1 + (cot^2 theta/ (1 + cosec theta)) = cosec theta

Prove that cot^4 theta+ cot^2 theta= cosec^4 theta-cosec^2 theta

cosec^(2)theta-cot^(2)theta-1

Prove that cot 2 theta + tan theta = cosec 2 theta

If cosec theta + cot theta= 2.5 , then cosec theta = ?

Prove that cosec 2alpha = cot alpha - cot 2alpha . Hence or otherwise prove that cosec theta + cosec 2theta + cosec 4theta + cosec 8theta = cot theta/2 - cot 8theta .
