साबित करें कि `1 + tan theta tan 2 theta = sec 2 theta `

prove that 1+tan theta tan2 theta=sec2 theta

Prove that :1+tan theta tan2 theta=sec2 theta

Prove that 1 + tan 2 theta tan theta = sec 2 theta .

Prove that (1+ tan^4 theta)/(1+ tan^2 theta) = sec ^2 theta-2 sin^2theta

( sec theta + tan theta -1)/( tan theta - sec theta +1)

prove that : (tan 2^n theta)/(tan theta) = (1+sec 2theta) (1+ sec 2^2 theta) (1+sec 2^3 theta) … (1+ sec 2^n theta)

prove that : (tan 2^n theta)/(tan theta) = (1+sec 2theta) (1+ sec 2^2 theta) (1+sec 2^3 theta) … (1+ sec 2^n theta)

Prove the following : (tan^3 theta -1)/( tan theta-1) = sec^2 theta + tan theta

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