Just to let you know that I managed to make a program which finds the minimum values of x and y given a value of D thanks to your explanation. I would definatley have gotten stuck on the if k is even thing. I still don't understand why it should make a difference. Anyway thanks again :smile:.
Ok, I've done a lot of searching and looking around but I cannot find anything that I can make sense of. The Pell equation I want to solve is this:
x^2 - Dy^2 = 1
Given an integral value for D that is not a square number, find the minimal values of x and y where x and y are both...
I would have thought this had been discussed before but I could not find any references to it in the search.
Basically, what on earth is this website all about?

It has many examples which claim to disprove or disrepute common well...
Watch a car overtake you on a motorway. Quite often the wheels of the car appear to be going backwards or even to stop. I suspect experiments of this nature could be used to find how quickly we see things.
