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

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

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

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

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

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

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

csc^(6)theta-cot^(6)theta=1+3csc^(2)theta cot^(2)theta

If cot^4 theta+ cot^2 theta=3 then 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^4 theta-cot^4 theta=cosec^2theta+cot^2 theta
