ff tan theta+sec theta=l," then prove that "sec theta=(l^(2)+1)/(2!)

if tan theta+sec theta=l then prove that sec theta=(l^(2)+1)/(2l)

if tan theta+sec theta=l then prove that tan theta=(l^(2)+1)/(2l)

prove that (tan theta) / (sec theta -1) = (tan theta + sec theta + 1) / (tan theta + sec theta - 1)

If tan theta + sec theta = n, then sec ^(4) theta - tan ^(4) theta- 2 sec theta tan theta =

If sec theta=x+(1)/(4x), then prove that sec theta+tan theta=2x or (1)/(2x)

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

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

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