there is any code for converting hyper-->trig?

a while ago there is a code for changing function from trig to hyperbolic and viceversa but i can't find that code except changind xi=I*xi there is another one?

Greek letter xi

EdVeling — Fri, 03 Apr 2026 13:12:22 Z

Sirs,

Today I encountered the following issue. I am working in a Maple worksheet with the variable "xi", which looks as ξ on the Maple output screen.

I am also working in LaTeX with the aid of Scientific Word, a LaTeX-interpretator.

I copied an expression from the screen (Scientific Word) containing the letter ξ (in LaTeX \xi, on the screen as the letter ξ) and put that expression in my Maple worksheet. In the output screen of Maple my variable "xi" and the copied expression from LaTeX (ξ) looked exactly the same. However, for Maple those variables were different, respectively "xi" and "\316" as I noticed in my *. mw file.

My calculations caused my a problem, I did not get what I expected. Firstly, I thought I made somewhere a mistake but after all the copy from the screen in Scientific Word turned out to be the culprit. So, it is not wise to make a screen copy.

But, why are the two variables looking the same in Maple while they are not for the calculations?

Importing data txt files with a header ?

FDS_ERT — Fri, 03 Apr 2026 07:22:10 Z

Dear Power users, I probably have a stupid question. Till now I converted my data txt files first to excel to import them in maple 2026. I imagine there must be a better method. I have attached a sample file. As a side question is it possible to import several files at once? Thank you for your support

multi limit fail, but separate limits works

nm — Thu, 02 Apr 2026 22:38:47 Z

Maple 2026 and Maple 2025.2

Is this a bug in limit? or as designed?

Doing

limit(sol,[_C3 = 0, _C4 = 0])

Gives internal error. But

limit(sol,_C3 = 0);
limit(%,_C4 = 0);

works and no error.

Worksheet below. I've had problems before with multilimit. I think I need to change my code to do limit one by one from now on.

>	interface(version);

restart;

>	sol:=(piecewise(t <= 0,0,t <= Pi,(arctan(tan(t))cos(t)_C3_C4+arctan(tan(t))sin(t)_C4^2-cos(t)_C3_C4t+sin(t)_C3^2t)/(_C3cos(t)+_C4sin(t)),Pi < t,Pi_C3(tan(t)_C3-_C4)/(tan(t)_C4+_C3))+2_C3^2+2_C4^2)(_C3cos(t)+_C4sin(t))/(2_C3^2+2*_C4^2)

>	limit(sol,[_C3 = 0, _C4 = 0])

Error, (in limit/multi/ldegree1) invalid input: limit/multi/ReIm expects its 1st argument, f, to be of type polynom, but received _DIR1*cos(t)+_DIR2*sin(t)

>	limit(sol,_C3 = 0)

>	limit(%,_C4 = 0)

Automating Maple-to-LaTeX workflow

salim-barzani — Tue, 31 Mar 2026 17:33:50 Z

Dear MaplePrimes Community,

With the rapid advancement of technology, it has become increasingly important to improve our workflows and reduce repetitive manual tasks. In my research, I frequently use Maple to solve PDEs and obtain analytical solutions. However, one major difficulty I face is the time-consuming process of manually converting each result into LaTeX format.

In many cases, Maple produces multiple solutions, and I must copy and convert each one individually into LaTeX. This process is tedious, inefficient, and prone to formatting errors.

Therefore, I would like to ask:

Is it possible to establish an automated link or workflow between Maple and LaTeX such that, after solving a problem in Maple, all resulting expressions are automatically exported and inserted into a LaTeX document in the desired format and location?

Ideally, I am looking for a system where:

Maple solutions are automatically converted into LaTeX code,
The equations are directly placed into a specified LaTeX file or section,
The process works for multiple solutions without manual intervention.

Furthermore, if such integration is possible, can this idea be extended to connect Maple with multiple tools (for example, Maple → LaTeX → plotting or document-generation systems), creating a more advanced automated workflow?

I would greatly appreciate any guidance, examples, or best practices for implementing such a system.

Thank you very much for your help.

problem with rsolve and GuessRecurrence

Hello :)

I am totally lost with ( I guess) the LREtools package.

See the ws.

The two integer sequences come from the OEIS.

I don't understand why i have a FAILED result.
