cos^(2)theta+cos^(2)theta cot^(2)theta=cot^(2)theta

cot^(2)theta-cos^(2)theta=cot^(2)theta*cos^(2)theta

Without expanding show that: =|cos ec^(2)theta cot^(2)theta1cot^(2)theta cos ec^(2)theta-142402|=0

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

Prove that cos^(2)theta("cosec"^(2)theta-cot^(2)theta)=cos^(2)theta .

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

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

Prove the following identity : cot^2 theta- cos^2 theta= cot^2 theta cos^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

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

If cot theta=sqrt(3), find the value of (cos ec^(2)theta+cot^(2)theta)/(cos ec^(2)theta-sec^(2)theta)
