You did not give a motivation why you use min in your example on a list without units. I  assume that you want to use min on lists with and without units after loading the simple package.

Until the bug is fixed you could call the default environment for lists without units by adding the prefix :- to min:

with(Units[Simple]);
:-min(0, 0);

I run your code in Maple 2023 and have corrected a few errors. What I did is highlighted in oragne.

I had no time to check why A is larger than 1 but maybe my touchups help in further analysis.

Alt s with the search term "conic" provides some usefully resources.

For algebraic expressions help(geometry,conic) provides ouput like this:

You may perhaps not have noticed that the call print[-2]() sets the interface variable prettyprint.

Calling print without argument is maybe not an intended use.

I will send a software change request for the interface prettyprint call.

I tried 2022 and 2023 with the same outcome that you described.

Maybe I found an explanation why Maple.ini does not work:

Any Maple command in Maple.ini, Startup Code and userprofiles is passed directly to the kernel (but not via the GUI).

Typesetting:−Settings(parserwarnings=false): seems to instruct the GUI not to issue a warning on the input (before the command is send to the kernel).

If this is correct, you are looking for a new feature that initializes the GUI. Kind of a GUI.ini or a button (maybe I overlooked it) in the options.

Try

Optimization:-Maximize(y)

I forgot:

From help(Temperature)

Combinations of Temperature objects that are neither affine nor null can be valid as intermediate results of a computation, but they do not typically represent physical concepts. In order to indicate this, they are displayed in red.

combine does remove the unit K in the brackets of the temperature object and adds a unit m (do not ask me why) and then turns everything into red to warn the user).

Instead of using a temperatur object I inserted 90 F from the units pallete. This works and no red output is returned.

If you want to use a previously defined temperature object you can to do it this way.

Temperature(90, Unit(degF));
params := n = Unit('mol'), T = Value(%)*Scale(%), P = 101325*Unit('Pa'), R = evalf(Constant(R, units));

For the second remaning question use convert or simplify

I had this issues on Windows 10 more than 2 y ago and than it dissaperad as it came.

At the time I attributed this to something on the system level when Windows file explorer was attemtping to connect to network drives (which were temporailiy not available).

About a month ago, I had the problem again and did what Joe Riel suggested. I also noticed that the problem occurred right after system restart and it took a while for Maple to start the first instance of mserver.exe (maybe there is some house keeping going on in the background). After that, Mapel worked fine.

At least I am not the only one.

To plot the Maple onliner

plot3d(-2 - sqrt(3)*tanh(1)*tanh(n - 6*tanh(1)*t), t = -5 .. 5, n = -5 .. 5)

something like that should work

% plot grid
t = linspace(-5, 5, 100);
n = linspace(-5, 5, 100);

% compute plot grid values
[T, N] = meshgrid(t, n);

% compute Z values
Z = -2 - sqrt(3)*tanh(1)*tanh(N - 6*tanh(1)*T);

% plot
surf(T, N, Z);

(I don't have Matlab running to test.)

For anything beyond, a Matlab forum can probably provide more answers.

should give you the answer

with(geometry);
_EnvHorizontalName := 'x';
_EnvVerticalName := 'y';
ellipse(p, ['foci' = [[-1, -1], [1, 1]], 'MinorAxis' = 2*sqrt(14)]);
Equation(p);

but does not accept the way I define the foci... Maybe someone can tell whats wrong with it

I do not think that this is an OS issue: I have it on Windows 10 as well.

I assume that this is more an issue of the new Java platform. Here the older platform

There is a global solution (on Windows) you probably don't like:

Reduce the display resolution of the system. When I change form 4K to 2K the tiny rendering is gone.

I am looking forward to Maple 2024, provided Maplesoft can do something about it and its not Oracle.

To your second question (clippings from the Maple Flow user manual): You have to browse Maple commands that you can find on this website.

You can use most of Maple commands

If you set the plot option adaptive to false the effect disappers.

For this one no simplified result is returned (Maple has no answer for that)

For that one the calculator returns

If you want the later one make sure (with the arrow up button) that the cursor is still in the exponent before you type -1.

I am using here Maple but have tested it also with the calculator.

to avoid complex explanations with branched solutions.

In the real domain with

plots:-inequal(a < cos(x), x = -6 .. 6, a = -3 .. 3)

solutions are located here:

Applying now arccos to both sides of the relation and flipping < to > because of the negative slope of arccos (and inverting the axes):

plots:-inequal(arccos(cos(x)) < arccos(a), a = -3 .. 3, x = -6 .. 6)

gives a better view on all solutions for a given a. The simple solution you have derived by hand looks probably something like this

map(arccos, cos(x) < a);
simplify(%, symbolic);

plots:-inequal(x < arccos(a), a = -3 .. 3, x = -6 .. 6)

This depicts the problem with your apparently simple relation to solve: You have to restrict this not only to a but also to x.

plots:-inequal(abs(x) < arccos(a), a = -3 .. 3, x = -6 .. 6)

The plotted solutions above do not reflect the periodicy of all solutions. I think that's the reason why you got the message about potentially lost solutions. Why Maple does not provide at least one of these two solutions

solve(abs(x) < arccos(a), x)

is up to someone else to explain
