If P,Q be variable points on a conic l/r=1-ecos∅ with vectorail angles alpha and beta where aplha -beta =2×gama=constant, then show that the chord PQ touches the conic l/r cos(gama) =1-ecos(gama)cos∅ and that this conic has the same directrix as the original one
Sir solve this problem

[@MATHAtoZRKPATRA]

Sure.
I will try.
Please wait
