Re: Problem 027

In summary of/to Lucas-C 's challenge -- In a graph of a,b pairs such that prime P = N^2 + aN + b for -100 <= a <= 100 and 0 <= b <= 2000 and such that the number of Ps for consecutive values of N is greater than 15, for example... Why is an apparent parabola displayed? I used the same graphical app...

Posting graphs in PE.chat...

Can anyone please explain to me how I can get a graph in
MS/Excel to post in PE.chat?

I read about the public WebSite requirement but
that is... Greek to me...

Thanks in advance,

Re: Problem 027

Speaking of PE27 and parabolas, came across this definition of a parabola's equation -- The standard form is (x - h)^2 = 4p (y - k), where the focus is (h, k + p) and the directrix is y = k - p. If the parabola is rotated so that its vertex is ( h , k ) and its axis of symmetry is parallel to the x...

Re: Problem 027

Thanks Much jaap...

I will do that next, even at 1am here on the USA's West Coast; and,
my compliments to you for finding that and to
hk for pre-addressing Lucas-C's question!!

Happy Polynomial Holidays,

Thanks jaap...

If you'd care to elaborate on such a simple relationship @ PE.net,
I would sure appreciate it, as I imagine
Lucas-C would too...
