If sin theta + cos theta = m and sec theta + "cosec" theta = n, prove that n(m^(2)-1) = 2m.

If sin theta + costheta = m and sin theta - cos theta = n , then

If sin theta + costheta = m and sin theta - cos theta = n , then

If sin theta + cos thea = m and sec theta+ cosec theta = n , then n (m + 1) (m - 1) =

If sintheta +cos theta =m and sec theta + cosec theta =n then n(m+1)(m-1) equals

If m= sin theta+ cos theta and n= sec theta+cosec theta , prove that n (m + 1) (m-1) = 2m .

If sin theta+cos theta=m and sec theta+cos ec theta=n then n(m+1)(m-1) equals

If cos ec theta - sin theta = m and sec theta - cos theta = n, then show that (m ^(2) n ) ^(2//3) + (mn ^(2)) ^( 2//3) = 1.
