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

cosec^(6)theta-cot^(6)theta-3cot^(2)theta.cosec^(2)theta=?

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

Evaluate : |{:(1, cosec ^(2) theta, cot ^(2) theta),(-1 , cot ^(2) theta, cosec ^(2) theta),(2,(9)/(2), (5)/(2) ):}| a) -1 b) 1 c) 0 d) None of these

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

Prove that cot^(4)theta+cot^(2)theta="cosec"^(4)theta-"cosec"^(2)theta

The value of 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) is-

"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)=
