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

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

Prove that (1-tan^2theta)/(cot^2theta-1)=tan^2theta,thetane45^@ .

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

Show that, (1+tan^2theta)/(1+cot^2 theta)=tan^2theta

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

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

"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)=

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