```										Let Point P is (ct1,c/t1)
Point Q is (ct2,c/t2)
Point R is (ct3,c/t3)
Point S is (ct4,c/t4)

slope of chord PQ is = -1/t1t2
slope of chord RS is  = -1/t3t4
both chord are perpendicular so
-1/t1t2  X -1/t3t4  =-1
or t1t2t3t4 =-1
now slope of CP =1/t12
now slope of CQ =1/t22
now slope of CR =1/t32
now slope of CS =1/t42
so product of slope =1
