# list of points of intersection

lawrence shared this question 3 years ago

need to know how to get the list of all points intersection between the upper part of the circles and the corresponding perpendicular lines.; only managed the botton set of points of intersection(l4.)

Any help or suggestion is much appreciated. thanks l4 = Sequence(Intersect(Element(l3, n), Element(l2, n), 2), n, 1, 8, 1) for upper

l4 = Sequence(Intersect(Element(l3, n), Element(l2, n), 1), n, 1, 8, 1) for bottom

l4 = Sequence(Intersect(Element(l3, n), Element(l2, n)), n, 1, 8, 1) default value for 3. parameter is 1 -> for bottom

l4 = Sequence({Intersect(Element(l3, n), Element(l2, n))}, n, 1, 8, 1) with {} -> for both as list (in the list)

----------------------------

{Intersect(a,b)} see notes in manual 1
