Answer:
L.H.S. = x2 – y2
= (p sec θ + q tan θ)2 – (p tan θ + q sec θ)2
= p2 sec θ + q2 tan2 θ + 2 pq sec 2 tan 2 -(p2 tan2 θ + q2 sec2 θ + 2pq sec θ tan θ)
= p2 sec θ + 2 tan2 θ + 2pq sec θ tan θ – p2 tan2 θ – q2 sec θ – 2pq sec θ tan θ
= p2(sec2 θ – tan2 θ) – q2(sec?2 θ – tan2 θ) =
= p2 – q2 …[sec2 θ – tan2 θ = 1
= R.H.S.hii
