I have not found a simple way to change the colors within Maple.

However, there is a way you can hack a set of different colors onto the screen. Mine is a set of coffee cream colors. Note:
1) You can't set individual colors. Rather, you load a set of predefined window colors.
2) This hack has only been tested on an MS Windows environment.
3) I sincerely doubt it is endorsed by Maplesoft. 
4) It does not always work. The worst outcome is that you end up with the standard set of colors.

To hack a set of new colors for the environment:
0) Close all Windows of Maple.
1) Locate the user preference file for Maple. This file is called maple.ini, but it is not the "initialization file". https://www.maplesoft.com/support/help/Maple/view.aspx?path=worksheet/reference/preferencesfile
2) Copy the file from the directory, which may be hidden, onto the desktop. 
3) Edit the file using a text editor. 
4) Find the term "GUITheme". (If not present, see instructions below.)
5) Change the name of the skin to a different skin name. (See list below.) My personal preference is Coffee Creme as in:
GUITheme = org.pushingpixels.radiance.theming.api.skin.CremeCoffeeSkin
6) Save the file on the desktop.
7) Copy the file back to the directory.
8) Open Maple. You should see a different skin color than the business blue.

4) If the term "GUITheme" is not located, after the line "AutoSaveEnabled=true", add, on a new line, the phrase:
GUITheme = org.pushingpixels.radiance.theming.api.skin.

Some popular skins, not all have been tested, and some I do know fail. (* work for me.)

• Business
• Business Blue
• Business Black Steel*
• Creme
• Creme Coffee*
• Emerald Dusk*
• Field of Wheat
• Magellan
• Mariner
• Mist Aqua
• Mist Silver
• Moderate
• Office Blue 2007
• Office Silver 2007
• Office Black 2007
• Raven
• Sahara
• Sentinel
• Sunset
• Twilight

To add a skin, write the name and include the word Skin, such as:

GUITheme = org.pushingpixels.radiance.theming.api.skin.EmeraldDuskSkin

See the document for information about the useful procedure evalc. I like it because it presents the complex expression in the format of a + i b.

Double-click on the title bar at the top to maximize the window. That usually works.

Delay the evaluation of the modp procedure in the product using 'modp' in FB. Then, FB := 2.

Go to https://www.gould.prof/learning-maple, and at the bottom of the webpage are a video and PDF examples of generating Mandelbrot sets.

I would use a combination of @dharr 's solution and your presentation. dharr's shows the value of Maple, and yours shows how one can think about the solutions that Maple returns.

Simple solution: double-click on the title bar, and the app fills the screen, causing the missing buttons to appear. 

LOL! This problem appeared today in my class after I changed the display size.

Double-click on the tabs to change the state of the ribbon.

1) Hit the Alt button
2) hit the I button (for insert)
3) hit the S button (for section)
4) hit <enter>

To answer your question on how to insert a constraint, I recommend inserting a piecewise operation into the inner summation.

ic2 says to take the derivative of u(x, 0) with respect to t, not take the derivative of the function and evaluate at t =0.

For ic3,

u__t is a name and is not u.

Webinar = web-based seminar.

A seminar is an event where speakers present content. 

You will receive a link to show up on your favorite device for viewing video at the time of the webinar. Click on it just before the event starts. 

The event will likely be recorded and uploaded to the Maplesoft YouTube account, but not until later. You are one of the lucky few who have been invited to see the new Maple features just before Maple 2025 is released.  

Try it! Have fun!
