If denote the lengths of the perpendiculars from the origin on the lines and respectively,
detailed solution
Correct option is C
p12+p22=4a2sec2α+cosec2α+a2cos22αcos2α+sin2α =a2sin22α+cos22α=a2and p12p22=a4sin22αcos22α=(1/4)a4sin24α∴p1p2+p2p12=p12+p222p12p22=4sin24α=4cosec24α.Talk to our academic expert!
