Hi MaplePrimes,

I'm trying to explore the polynomial r = n^2+n+39.  where n is an integer

I want restrictions on n such that r will factor into two trinomials.

Here is how far I got -

The 'has' function may be helpful.

Any help is appreciated.

Matt

 

Hi Maple experts and others,

We want to make a graph with 6 vertical lines.  One end of every vertical line will be on the x axis.  The other end of the vertical lines will be on integers of data points.

 


 

3+2

(1)

ab := Vector[row](6); cd := Vector[row](6)

ab := Vector[row](6, {(1) = 5, (2) = 8, (3) = 11, (4) = 14, (5) = 17, (6) = 20})

 

cd := Vector[row](6, {(1) = 1, (2) = 2, (3) = 3, (4) = 4, (5) = 5, (6) = 6})

(2)

for count to 6 do ab[count] := 3*count+2; cd[count] := count end do;

Hi Maple Experts and all,

 

There is a conjecture from a book written in 1986.

This conjecture states that

"Given any four consecutive integers greater than 11, there is at least one of them that is divisible by a prime greater than 11."
 

Is anyone willing to write Maple code to test this up to a reasonable numerical limit?

See a discussion thread

https://mersenneforum.org/showthread.php?p=518300#post518300

I imagine the ifactor() command and loops.  I'm not that good at coding.

Matt

Hi all,

For what its worth,
I want to make a graph of data.
Attached is file to show how far I got.
