From time to time Maple output containts brackets that are nor needed. Example:

int(f(x),x=a..c)-int(f(x),x=a..b);
simplify(%) assuming c>b

Why is that? Is there a way not to have these brackets printed?

eqs := [a = b, c = d, e = f]:

map(`+`, eqs, 2);
map(`-`, eqs, 2);
map(`/`, eqs, 2);
         [a + 2 = b + 2, c + 2 = d + 2, e + 2 = f + 2]

         [a - 2 = b - 2, c - 2 = d - 2, e - 2 = f - 2]

               [1     1    1     1    1     1  ]
               [- a = - b, - c = - d, - e = - f]
               [2     2    2     2    2     2  ]

These work differently

map(`*`, eqs, 2);
map(`^`, eqs, 2);
               [2 (a = b), 2 (c = d), 2 (e = f)]

Error, non-algebraic base in a power: a = b

(The first one can be dealt with by applying eval to the output)

Why do not all work the same way?

Edit:
Generic work arounds where arithop is one of: + - / * ^

map(eval@`arithop`, eqs, 2);
map(map@`arithop`, eqs, 2);# Update: Maple 2021 and higher
[seq(i arithop 2, i in eqs)];

I experience Maple 2024 not beeing responsive.

It happens often that nothing is happening for 10 to 15 seconds after placing the cursor in an input line.

When the cursor is back, typing is normal for a little while and then again Maple is not reacting to user input.

The worksheets I am working with are between 50 and 100 Mb large in file size (containing plot3d structures, approx 1000 frames distributed across several plots:-display statements). It looks to me that the GUI has to do some house keeping from time to time which keeps it buisy with all the plot structures.

I could delete (plot) output, but this would require execution of the worksheet (before deleting the output) each time I want to continue working normally. This takes several minutes to be ready to work.

Anything else that I can do?

In the attachment are three plotting issues that might be (partially) related.

 
Jagged shading     

Loss of color and incomplete clipping

The last one is the most severe because it takes color away when a plotobject is inside another object.

How can this be fixed? Explanations always welcome.

Looks like this

From: dsolve_numeric_output_with_extra_brackets.mw

which was derived from a 2d document where I removed all unnecessary overhead.

When the option output=listprocedure is removed, this extra argument is not shown any more.

With that extra argument substitution of a solution into the corresponding ode(s) is not possible.

Any idea why that is? How to avoid or remove it?
