	n^2+n-1 has no divisors ending with 3 or 7		2005-09-08
		Arne pose la question : at least it seems like for any integers n and k, 10k+3 and 10k+7 do not divide n²+n-1 I tested this for every n from 0 to 3200 (which means same for the numbers from -3201 to -1) could this be true, or is it just coincidence, or am I just totally wrong? Richard McIntosh lui répond.

	x = (y^2 - b^2)/2b		2005-09-04
		Bob pose la question : while looking at x=(y2-b2)/2b on a table I was preparing for a graph, I saw that there is a point where x and y get closer to each other's value. By trial and error I tried to find the point where x=y. I saw a number which looked familiar and I realized it was the square root of 2. and so, if y=b(1+square root of 2) then x=b(1+square root of 2) also, or as x=y. My question is: How can this result x=y when y=b(1+square root of 2) be algebraically derived from the equation x=(y2-b2)/2b without pre knowing it is so? Penny Nom lui répond.
