Is there any equation for how many times lines can cross over each other if they have to be straight, and each one starts where the one before it ends, and the last line ends where the first line begins? To contruct this:
1. Draw a straight line.
2. Now, from where the first line ends, draw another sraght line to somewhere else.
3. Do this at least four times.
4. The last line that you draw has to end where the first one began.
5. Try to make any there be as many intersections between lines as possible.
The question is, is there a function that defines the maximum number of intersections y for the number of lines drawn x?
The domain is four and up.
The first few points are:
(4,1)
(5,5)
(6,7)
