Just for my interest.
Why is the following not working

one := ``(1);
                           one := (1)

 lprint(`%`);
Error, Got internal error in Typesetting:-Parse:-Preprocess : "invalid subscript selector"
Typesetting:-mambiguous(Typesetting:-mambiguous( lprint(%), 

  Typesetting:-merror("Got internal error in Typesetting:-Parse:\

  -Preprocess : "invalid subscript selector"")))

but this works

lprint(one);
``(1)

Hi,

I am working on an exercise involving sequences of complex numbers, with the goal of animating the resulting spiral and possibly displaying the right triangles originating from the origin. I am looking to improve my animation to make it clearer, more visually appealing, and easier to interpret.

Thanks for your help !

I was atttempting to ask a question about I problem with styles in the editor in Maple 2026. When I attempted to upload a worksheet  showing the problem, my upload was blocked (SQL injection detected). The worksheet is question was, so far as I know, a standard Maple Worksheet containing a module in the start up code editor. How do I successfully upload a maple worksheet?

I do not understand why a once entered prompt cannot be copied from the AI pannel.

I also do not understand that a text passage from an answer (e.g. a proposed help topic) cannot be selected and copied to the clipboard with crtl-c.

It does not make sense to me to unnecessarily restrict a new program feature. This somehow spoils the show.

Is that a restriction to Windows or my local setting or something imposed on Maplesoft from a third party supplier?

Has anybody seen similar AI implementations in other products?

Recent I purchased maple with order 24780207. Should you send me the receipt of my purchase

Regards

Derive simplifies directly to (1 - a)^3 .

Hello Ladies and Gents :)

I asked Maple AI to write a program to calculate the geodesics on a sphere.

see the attached ws.

When running this program I receive an error which I don't understand.

of course i know how to do it by paper and pen, it was just a test.

if someone could explain me this error i would greatly appreciate .

thank you and kind regards,

Jean-Michel

Hi Maple Flow users,

Today I was making a canvas covering the theory regarding transformers. I use units in my computations, and this is carried onto any plots I make. While I have figured out that the unit I use while defining the plot range on the x-axis is carried onto the plot, I am yet to figure out how to define the unit used on the y-axis.

Please have a look at this snapshot:

The y-axis unit is defined as kg/(A*s^2), while it should of course be in T (Teslas). How would I go about realising this?

And of course, if you have any other tips and tricks related to these kind of plots please feel free to share them :))

Kindly,
Asger

In the attached file, I would like to practice calculating distances between the exact and approximate functions using the "Minimize" function. However, the approach using the integral metric according to (4) produces an error message. I am unable to correct this and would appreciate some advice.test.mw

I have installed Maple Flow 2025 as a trial but have not been able to get the migration assistant add-on.

As part of evaluating Maple Flow, it is critical for me to try conversion of Mathcad 14 files.

Thanks.

Here is another case where an incorrect solution of a non-algebraic expression is returned.

How to make Maple exclude solutions obtained with allsolutions where the expression is not defined?

IMO, allsolutions facilities of Maple should do this automatically. Anything from a mathematical point of view that speaks against an automatic exclusion?

(Are there other commands that provide a correct solution?)

By the way:

solve(sin(x)/x)

does not return a single solution as stated on the solve help page ("In general for transcendental equations, the solve command returns only one solution,...") because solve correctly discards x=0 but does not consider returning x=pi.

Related topic: I also think that new users and students should profit from a directly understandable output like this

Maybe adding new convert form is an option.

I calculate a long polynomial p(x) where the coefficients depend on a varaiable d. That takes about 10 minutes. I put a colon at the end of the computation because the result is very large. Then I put d=12.2 say and proceed to do a lot of other things. All well and good. I save the file as fooapril23 and go home. When I return I want to repeat the computaion with d=12.5 which I can do by opening the file, saving it as fooapril24. Then I have to recalculate p which is 10 mintes wasted until I can say d=12.5 and proceed with my work..  I would like to "park" the result for p in a file somewhere and then import it when needed. I went to the read and writeto help pages but could not understand it at all. (I tried bit when I did the writeto command and then opened a new worksheet and tried to read I got an error:

Error, on line %1, syntax error, `>` unexpected:

(The > was the Maple prompt I guess.)

I have tried over the years to use the writeto and read commands but I think the help pages are written for unix gurus and I am a Mac user.

BTW I am using Maple 2026 My worksheet starts with > restart; Digits:=20: with(Plots):
I guess requiring the with(Plots): command in 2026 is some kind of an in joke?

I do have a stundent license permanently and I've installed the OpenMaple java examples: JCEngineCallBacks, JCHelpCallBack, jcmaple in Eclipse.

I've also installed the MapleTest.java which runs fine.

When I start the jcmaple.java I get the error: license communication problem 1  Error starting OpenMaple session

So I don't know why.

Meanwhile I was able to solve the issue

Maple 2026 crashes. I had to use this

PackageTools:-Install("https://maple.cloud/app/4797495082876928/Maple+Customer+Support+Updates",overwrite=true)

Is that issue known?
