"Identify" for sequences of numbers?

Alfred_F — Tue, 13 Oct 2026 07:29:10 Z

While practicing with the "identify" command, I came across the question:

Does Maple offer a way to determine the generating rule for a sequence of numbers given by a finite initial segment?

Here is a riddle for this:

The sequences {s_n} = 1/1; 1/2; 1/3; ... and {t_n} = 0/1; 1/2; 2/3; 3/4; ... have the formation rules

s_n = 1/n and t_n = (n-1)/n.
What is the formation rule for the sequence {u_n} = {s_n; t_n} formed by alternating between the two?
Note: The solution is not u_2n = t_n and u_(2n−1) = s_n. Rather, the goal is to find a single, unified formation rule u_n that yields the terms of the combined sequence for n = 1; 2; 3; ...

Series simplification performance

segfault — Mon, 12 Oct 2026 18:11:30 Z

If I compare Maple 2024 and Maple 2022 on the exact same worksheet, Maple 2022 executes twice as fast as Maple 2024.

For my kind of work this is very serious. I have programs that can take 10 or more days to complete calcuations, therefore what Maple 2022 will calculate in 10 days, Maple 2024 takes 20 days. It has wasted a LOT of my time, whatever the reason is.

Here is the code:
1) MM must be a high order series expansion with complex arguments so that simplification is not trivial. Use any such asymptotic expansion.
NOTE: I can supply an expansion for a developer through official Maple support, but cannot release it publicly as it is part of a future publication. It is easy enough for anyone to create a complex expansion, with difficult simplification.
2) The simplification of the expansion must at least take a couple of minutes at e.g. Order=10 for the comparison to make sense.
3) Then run the program for Maple 2022 and Maple 2024 respectively and note execution time.
4) This was run on Linux.

As you will see the Maple 2024 calculation takes twice as long as the Maple 2022 calculation.
SEE RESULTS AT END OF PROGRAM.

testorder:=6; # Enter the expansion order here.
MM:=??: # Enter the expansion here.
series(MM, x = 0, testorder):
convert(%, polynom):
map(simplify, %):
#collect(%, x, simplify):
simplify(%):

testorder := 6

RESULTS:

Updates of the Mathcad Migration Assistant?

JABova — Mon, 12 Oct 2026 13:43:56 Z

I'm a long time Mathcad user and have considered migrating to Maple/Maple Flow. About a year ago I did a trial and found that there a number of Mathcad constructs that need manual conversion to function in Maple Flow so I chose to wait.

I saw a comment by Samir made on Maple Primes in July of this year that a new version of the Migration Assistant was just about ready for release. Can you let me know if that has happened and point me to a list of changes? I'm considering pulling the trigger on another round of testing and was hoping that some of the gaps have been closed. As an example of things that that required attention were iteration variables, handling of Vectors, unit/constant handling (especially Mathcad global definitions), and migration of graphs/plots.

I know that there are workarounds for all of these things - I'm not seek those specific solutions - just and update on the possible changes

Thank You!

Edge lengths of a rectangular prism

Alfred_F — Fri, 09 Oct 2026 14:54:43 Z

With thanks for the advice regarding quadratic Diophantine equations and tabulation, here is a little puzzle:
For a rectangular cuboid, the length of the space diagonal is known to be 90 cm and its surface area 8800 cm². Determine its integer edge lengths.

How is the data tabulated?

Alfred_F — Tue, 06 Oct 2026 14:07:19 Z

In the attached file, I would like to create a table of values (k,f(k),g(k)) for the functions f and g for, e.g., k=1..10. I would appreciate your help with this, as f and g refer to reciprocity in their expressions.
