cot theta[cot^(2)theta-1]

Solve: cot5theta=cot2theta

Solve: cot5theta=cot2theta

If sin^2theta=cos^3theta prove that, cot^6theta-cot^2theta=1 .

If sintheta,costheta and tantheta are in G.P., then prove that cot^(6)theta-cot^(2)theta=1

(tan theta)/((1+tan^(2)theta)^(2))+(cot theta)/((1+cot^(2)theta)^(2))=sin theta cos theta

(cos^(2)theta-cot^(2)theta+1)/(sin^(2)theta+tan^(2)theta-1)=cot^(2)theta

If cot^4theta-cot^2 theta = 1 then show that sec^4 theta-sec^2 theta=1 .

Prove that : (tan^(2)theta)/(1+tan^(2)theta)+(cot^(2)theta)/(1+cot^(2)theta)=1
