My world of trigonometric functions has a very simple structure: sin, cos and tan are what I need.

That's why I very much welcomed the simplification of sin/cos to tan recently introduced with Maple 2023.

What I neither need nor want is the simplification of 1/sin and 1/cos to sec and csc. I'm not used to that (and probably won't get used to it).

Can this simplification to sec and ccs be turned off (and preferably the simplification to tan be kept)?

Another very strange behavior.

res:= x^2 + x + 1 + 1/3*x^3 + 1/12*x^4 + 1/60*x^5 + 1/360*x^6 + 1/2520*x^7;
sort(res);

#and now
res

Without trying it, what do you expect the output of the last line above to be?  The same as the first one, right?  But that is not what Maple gives. Maple now changes res to always be sorted, even though I have not reassigned it.

Does this mean if one calls sort(), then all the variables that contains polynomials will also be sorted automatically?

These give errors

limit(y(0),y(0)=1)

limit(y(x),y(x)=1)

Error, (in limit) limit variable previously assigned, 2nd argument evaluates to y(0) = 1
 

One has to write 

limit(y,y=1)

But why? Is this because y(x) is not considered "algebraic" ? 

Mathematica has no problem with either one of these

I found this when I was trying to find the limit at initial conditions, when x=0 and y(0)=1 and wanted to take the limit on both x->0 and y(0)->1 

I can easily code around this, by renaming y(0) to say Y0 and then the limit will work.

It just seems to be unnecessary restriction of the limit() command parsing ability. 

What is the logic behind not allowing one to write limit(y(x),y(x)=1) ? 

Just wonder if there are any known issues when using dots in Maple code attachment names?

Only issue so far that I can see is that error messages are split a bit strange.

How can i plot stream lines by using velocity components (tx+1, -ty-t^2)? or by stream function?

How can I animate the revolution surface around the red line?

While working a test workbook in Maple 2023 - added a file went away for a while and came back and started adding code to the workbook when I suppose it did an autosave and this error came up 4x in a row. 

Hi, 

I am stuck on how to graphically represent my two G and S shapes. Any suggestions to help me illustrate this concept of a ruled surface?

Thank you

The recent Maple 2023 release comes with a multitude of new features, including a new Canvas Scripting Gallery full of templates for creating interactive Maple Learn documents.

The Maple Learn Scripting Gallery can be accessed through Maple, by searching “BuildInteractiveContent Maple2023” in the search bar at the top of the application and clicking on the only result that appears. This will bring you to the help page titled “Build and Share Interactive Content”, which can also be found by searching “scripting gallery” in the search bar of a Maple help page window. The link to the Maple Learn Scripting Gallery is found under the “Canvas Scripting” section on this help page and clicking on it will open a Maple workbook full of examples and templates for you to explore.

The interactive content in the Scripting Gallery is organized into five main categories – Graphing, Visualization, Quiz, Add-ons and Options, and Applications Optimized for Maple Learn – each with its own sub-categories, templates, and examples.

One of the example scripts that I find particularly interesting is the “Normal Distribution” script, under the Visualizations category.

All of the code for each of the examples and templates in the gallery is provided, so we can see exactly how the Normal Distribution script creates a Maple Learn canvas. It displays a list of grades, a plot for the grade distribution to later appear on, math groups for the data’s mean and variance, and finally a “Calculate” button that runs a function called UpdateStats.

The initial grades loaded into the document result in the below plot, created using Maple’s DensityPlot and Histogram functions, from the Statistics package. 

The UpdateStats function takes the data provided in the list of grades and uses a helper function, getDist, to generate the new plot to display the data, the distribution, the mean, and the variance. Then, the function uses a Script object to update the Maple Learn canvas with the new plot and information.

The rest of the code is contained in the getDist function, which uses a variety of functions from Maple’s Statistics package. The Normal Distribution script takes advantage of Maple’s ability to easily calculate mean and variance for data sets, and to use that information to create different types of random variable distributions.

Using the “Interactive Visualization” template, provided in the gallery, many more interactive documents can be created, like this Polyhedra Visualization and this Damped Harmonic Oscillator – both from the Scripted Gallery or like my own Linear Regression: Method of Least Squares document.

Another new feature of Maple 2023 is the Quiz Builder, also featured in the Scripting Gallery. Quizzes created using Quiz Builder can be displayed in Maple or launched as Maple Learn quizzes, and the process for creating such a quiz is short.

The QuizBuilder template also provides access to many structured examples, available from a dropdown list:

As an example, check out this Maple Learn quiz on Expected Value: Continuous Practice. Here is what the quiz looks like when generated in Maple:

This quiz, in particular, is “Fill-in the blank” style, but Maple users can also choose “Multiple Choice”, “True/False”, “Multiple Select”, or “Multi-Line Feedback”. It also makes use of all of the featured code regions from the template, providing functionality for checking inputted answers, generating more questions, showing comprehensive solutions, and providing a hint at the press of a button.

Check out the Maple Learn Scripting Gallery for yourself and see what kinds of interactive content you can make for Maple and Maple Learn!

Maple 2023: The colorbar option for contour plots does not work when used with the Explore command. See the example below.

Hello

I am running Maple 2023 on a mac M1. When I ask Maple to print a document with 3D figures, only the axes come out. 2D figures come out fine.  If I do the same thing on Maple 2022 on the same machine, there is no problem at all.   

Can any one confirm this problem?

many thanks

Just installed Maple 2023 on Macbook Air M1.

Maple Tasks dosn't work :-(

Why???
Quite evidently, its supremum cannot be 0. (There are, of course, other approaches to compute it symbolically, yet I just wonder about the cause of this bug.)

Could someone explain to me why the Maple online help pages (see here) are still apparently matching the Maple 2021 release for the past few years? Does this mean that all the information on the Maple online help pages is out of date, or just this one specific page is terribly out of date?

I am trying make atomic variables stand out in the document, I thought they used to automatically change to a purple type colour.

So under Format, styles , I set the style to size 14, Bold, dark green.  The font changed on the existing ones but not the colour.

On new ones no setting occours just default text. I then restored to default settings under styles and they all turned purple including the new ones.

Then I made another one but no adoption of the default style (purple) occured. 

This fiddlyness needs to be improved  

Has anyone any suggestions to make the atomic variables adope their default colour etc?
