"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:

OPTION1 Calculation time for series MM,

Copying made tricky

awass — Fri, 09 Oct 2026 17:27:57 Z

I tried to copy a snippet of a maple command from a worksheet and paste it elsewhere in the worksheet and it was transformed into document form. I could not figure out how to fix that.It was worthless to me. For example, in the command I had "eval(f, [y=1,d=3])" and it became f| with the subscript y=1,d=3.

Also, I wrote "parametr" in a procedure and Maple rejected the command with a vague complaint. OK, my bad; garbage in garbage out, parameter not parametr, etc. BUT this is 2026! Autocorrect features have been around for years. Underlining of strange spellings are standard on word processors, phones , etc. Can't Maple catch up?

Edge lengths of a rectangular prism

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.
