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

(sec^(2)theta-sin^(2)theta)/(tan^(2)theta)=cosec^(2)theta-cos^(2)theta

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

Prove that (sec^2theta-sin^2theta)/tan^2theta=cosec^2theta-cos^2theta .

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

If 3cot theta=4 then show that (1-tan^(2)theta)/(1+tan^(2)theta)=(cos^(2)theta-sin^(2)theta)

If 1/(sin^(2)theta)-1/(cos^(2) theta)-1/(tan^(2)theta)-1/(cot^(2)theta)-1/(sec^(2)theta)-1/(cosec^(2)theta)=-3 then find the value of theta .

f(theta)=sin^(2)theta+cos^(2)theta+tan^(2)theta+sec^(2)theta+csc^(2)theta+cot^(2)theta then the minimum value of f(theta) is

Prove that : (tan^(3) theta)/(1+tan^(2)theta) +(cot^(3)theta)/(1+cot^(2)theta) = sec theta "cosec " theta - 2 sin theta cos theta .

"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)=
