Prove cos ec^(2)theta=1+cot^(2)theta

(cos ec^(2)theta-sec^(2)theta)/(cos ec^(2)theta+sec^(2)theta)=(3)/(4)

Prove :cos ec^(2)theta+sec^(2)theta=cos ec^(2)theta sec^(2)theta

Prove the following identities: (tan theta-cot theta)/(sin theta cos theta)=sec^(2)theta-cos ec^(2)theta=tan^(2)theta-cot^(2)theta

Find the minimum value of sin^(2)theta+cos^(2)theta+sec^(2)theta+cos ec^(2)theta+tan^(2)theta+cot^(2)theta

Prove: cos ec^(6)theta=cot^(6)theta+3cot^(2)theta cos ec^(2)theta+1

Show: 2sec^(2)theta-sec^(4)theta-2cos ec^(2)theta+cos ec^(4)theta=cot^(4)theta-tan^(4)theta

If p cos c theta+q cot theta=2 and p^(2)cos ec^(2)theta-q^(2)cot^(2)theta=5 then the value of sqrt(81p^(-2)-q^(-2)) is

cot^(4)theta+cot^(2)theta=cos ec^(4)theta-cos ec^(2)theta

If cos ec^(4)theta+cos ec^(2)theta=12+cot^(4)theta+cot^(4)theta then 6cos^(2)theta is equal to
