" सिद्ध कीजिए: "(1-cot^(2)theta)/(tan^(2)theta-1)=cot^(2)theta

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

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

(1)/(1+tan^(2)theta)+(1)/((1+cot^(2)theta))

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

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

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

(tan theta-cot theta)^(2)+2=tan^(2)theta+cot^(2)theta

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 .

If sin 2 theta=k then the value of (tan^(3) theta)/(1+tan^(2) theta)+(cot^(3) theta)/(1+cot^(2) theta)=
