gkokovidis  Thanks Georgios.  You exactly answered my question.

Hi Bendesarts

Not quite understanding the question but hopefully this image of maple code can shed some light on your situation.





oops.  I didn't really ask a question.

I meant to ask how to put this point plot in blue.




Hi esmerindobernardes    I have not read the two answers already posted.  Here are two techniques that helped me.  First   simplify your question.  Try eating a sandwitch or taking a nap.  Sometimes a walk outside helps.  Regards  Matt

There is almost nothing to add to this successfully answered question.  I noticed in the Maple help file that the command subs applies to expressions.  From school, I remember that the Dirac Delta is a distribution. 

For what its worth,


@mattcanderson1 Ok so I am replying to my own comment.  I found the textbook "Textbook of Conic Section by A.K. Sharma"  It is part of DPH Mathematics Series.  It was helpful.  The only problem is there are no excercises in this textbook.

@Kitonum thank you for the useful information.  I am still learning all the features of Maple.  Matt

Thank you for the prompt answers.  Can anyone suggest a textbook reference for parametric conics?


@rit I don't know the answer to your question.  Maybee you can save the data from Matlab to a file and then inport it into Maple.  (mabyee the 'read' or 'load' command .  See manual.)  For what its worth.  


@mattcanderson1 Carl Love is correct, this series is like the harmonic series, and it diverges.  Matt

Hi Fatyplus,

I want to make sure you know the complex number definitions of hyperbolic and regular trigonometric functions.

Also, Mathworld is helpful.  See expression (3)

Note that cos(x) = 1 has infinitely many solutions.  Namely,

x = 2*k*pi for k any integer.

My maple package ignores all but x=0.



Hi Muhammad,


Thanks for using MaplePrimes.  I downloaded your .mw file and repost as .jpg.

Do you want F(r,s) ; D(r,s) ; and the new F(r,s) to be integers?

What are you trying to accomplish with F and D?

@mehdi jafari 

here is my understanding of Maple isprime()

The isprime() function will first check if the input is a prime less than 100.
then it checks if it is divisible by a prime less than 100,
(it uses greatest common divisor and the product of the primes < 100 for this step)
then it checks if it is divisible by a prime less than 1000,
then it uses one Rabin-Miller test, and one Lucas test.

use the maple command showstat(isprime) to see the code.



I seem to have solved my problem.

I wrote some code for the Online Encyclopedia of Integer Sequences and made a longer sequence.

You can read my results here



I am replying to my own question a few hours later.

I ask maple isprime(m*n+o+p)

An example of correct offsets is here

pattern p = [0,2,6,12,14,20,24,26,30,32]

o= 167 with m=210

this refines to
o = [587,1007] with m=2310

this can be furthur refined.

I made my mistake when I was refining one step past this.
