Straight Lines!If I want to find out the distance between two points A and B by using parameteric form,if the point of reference(x1 in x1 plus minus rcos($),y1 in y1 plus minus rsin($)) and solve the quadratic in r and then difference of roots will give me AB.What if x1,y1 lies in between A and B?How can this give me my answer?
