Please see the attached worksheet:

Question 1:  How to plot a partial portion of an array s2 using "dataplot," say the first 50 elements.

Question 2:  I have also tried to use "plot" to plot the first 50 elements s2 and keep on getting errors or strange looking plot with horizontal lines.  I have tried plot(s2,1..50), plot(s2,x=1..50), plot(s2,m=1..50), plot(s2[m],m=1..50), plot(s2[1..50],1..50], plot(1..50,s2[1..50]).

How i can apply this transfromation which is special and i can't undrestand how from that solution he did thus changes  and get the solution of ode  ,  i reached untill eq(3.5) but after that i can't  figure out what he did   and how we get eq(3.7)-(3.9) (3.12),(3.13) and how we can   tranform solution  for the  eq(3.5)

To get better acquainted with "plot3d," I browsed through the help documentation. I was surprised to discover not only "Polyhedraplot," but—via "Polyhedra Sets" and "DualSet"—the very tools needed to tackle a classic subject: The duality of Platonic solids.
This reminded me of the following puzzle:
Consider the unit cube (edge ​​length = 1) and, situated within it, its dual polyhedron (the octahedron). As is well known, the dual polyhedron of the octahedron is, in turn, a cube. Now, let us continue this dual construction indefinitely, starting from the unit cube (cube containing octahedron containing cube containing octahedron...). This generates a sequence of nested polyhedra—alternating between cubes and octahedra.
1.) For each of the infinite subsequences—that of the cubes and that of the octahedra—calculate the sum of all volumes and surface areas.
2.) What is the maximum volume an octahedron (regardless of its orientation) can have while being completely contained within the unit cube?

I am very pleased to announce the publication of my new book written together with Nic Fillion, "Perturbation Methods Using Backward Error", which uses Maple heavily throughout.

You can find it at

the SIAM bookstore

and I hope that you find it useful and interesting.

You can also find a paper in Maple Transactions, written with Michelle Hatzel, that explains how we generated the image that was chosen for the cover.  Exploring Cover Designs for an Upcoming Book  In the end, the SIAM design people chose a different one than we had thought, but they did pick one of the ones we generated!  

This was fun to do.

Over the past few months, I've created a number of short videos. My intention is to help people use Maple more effectively. I occasionally give workshops introducing Maple and its programming language, and many of the topics come from questions I get from the participants. 

These can be found on our Youtube channel. Here are the ones posted so far.

Is the implementation of DataFrames in Maple antiquated compared to PANDAS or other modern implementations of DataFrames? Even doing the most basic tasks is extremely difficult or unintuitive. I have lived in the DataFrame help pages for 5 years and I still can't delete a column from a DataFrame. Will I ever get any work done?

Color option in Context Panel does not work

Steps to Reproduce:
1. Create or open a histogram.
2. Try to change its color using the Color option in the Context Panel.
3. Observe that the color does not change.
4. Click outside the histogram.
5. Click back on the histogram.
6. Try the Color option again — now it works.

Expected Behavior:  
The Color option should work immediately when applied to the histogram, without requiring extra clicks.

Actual Behavior:  
The Color option only works after clicking outside the histogram and then reselecting it.

In my opinion both these expressions should return false.

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 !

Maple 2026.1 

We have just released an update to Maple. Maple 2026.1 includes further enhancements to the new AI Assistant and Plotting Themes, as well as Explore, accessibility, and the math engine. As always, we recommend that all Maple 2026 users install this update. 

In particular, please note that this update includes a fix to the problem where titles do not show up when using the Explore commands title option.  As always, thanks for helping us, and your fellow Maple users, by letting us know! 

This update is available through Tools>Check for Updates in Maple, and is also available from the Maple 2026.1 download page on web site, where you can also find more details.  

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
