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)

tan theta+1/tan theta=2 then prove that tan^2theta+1/tan^2theta=2

prove that 1+tan theta tan2 theta=sec2 theta

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

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

prove that If tan theta + (1)/ (tan theta) = 2 then show that prove tan^2 theta + (1) / (tan^2 theta)

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

If csc theta-sin theta=l and sec theta-cos theta=m prove that l^(2)m^(2)(l^(2)+m^(2)+3)=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)
