`2cot^(2)theta="cosec"^(2)theta`.

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

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

sqrt(cosec^(2)theta-cot^(2)theta) is:

cosec^(4)theta+cot^(2)theta+cosec^(2)theta)"=

If "cosec" theta + cot theta = (13)/5 then cot^(2) theta - "cosec"^(2) theta = (25)/12

cosec^2 theta - cot^2 theta = 1 +…..

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

"cosec"^(2) theta * cot^(2) theta -sec^(2) theta * tan^(2) theta - (cot^(2) theta - tan^(2) theta ) (sec^(2) theta * "cosec"^(2) theta -1)=

Prove that (tan theta + cot theta)^(2) = "sec"^(2) theta + "cosec"^(2)theta = "sec"^(2) theta. "cosec"^(2) theta .
