Re: Problem 703

For those more conversant in Computer Science than Mathematics, the following translation of Problem 703 may be helpful, if not invaluable -- A k-input binary Truth Table is a map from k input bits (0=False; 1=True) to 1 output bit. For example, the 2-input binary Truth Tables for the logical AND a...

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...

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...

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,

I would sure appreciate it, as I imagine
Lucas-C would too...
