Just thought i would update you guys, i finished the assignment in time, even though i litterally re did the whole thing 4 or 5 times..
and i got 37/40 !!

Thankyou to gnitsuk!

lol, 'a brief history of time'... i think that might just be an oxymoron (2 words that contradict each other)
eg Government Organisation, Microsoft Works (my personal favourite), Butt Head... and so the list goes on

Just some (retarded) thought i chase around in my head when im board


If the Universe is always expanding, then there must be something outside of it to expand into...
whats outside of the universe...
why is there even a universe...
if there is something outside the universe then what is it...
assuming there is something outside the universe, why is that something there....
is that something inside of something else....
why does the universe even exist.....
if the universe didnt exist where would it not exist......
since the universe does exist where the *fudge* is it...

and so on in an endless loop....

anyone else ever had a retarded thought like that?

Correct me if im wrong...
the product of the gradient for a line multiplied by the gradient of the line's perpendicular bisector always = -1
so the if the gradient for AB = -3 then the product of -3 and the gradient of the line perpendicular to AB is -1 therefore  m*-3=-1  ..... m=(-1)/(-3) ..... m=1/3 so the gradient of the line perpendicular to AB = 1/3

Correct?

Ok, I understand
the equation of a straight line part
the gradient part (Rise/Run)
how did you get the product of the gradients of perpendicular lines?

When you say Voronoi edge of say AB, do you mean the perpendicular bisector of AB? And you know the corrdinates of A,B and C in the plane?

well, i assume thats what it means, yes, im pretty sure thats it...
and yes, i know the the coords
A (10,11)
B (11,4)
C (2,5)

Does anyone know how to "Determine the equation of the Voronoi edge for points A and B" ?

I have 3 points (A,B,C) and yes it is a poorly drawn ascii diagram

                                    A
                                      ^
                                   /60°\
                                 /         \
                               /             \
                             /45°       75°\
                           <____________>  B

as i said above, i need to determine the equation for the Voroni edges, initially i found the equation for the lines connecting A,B,C but i just realised what the question is asking and my assignment is due in 10 hours, oh and its currently 11pm so you may have figured im freaking out.

All help appreciated
