I aim to conduct a numerical frequency sweep analysis on a nonlinear, coupled two-degree-of-freedom vibration model and compare the results with the analytical solution. However, I am currently facing two main difficulties:

1. I am unsure how to determine whether the computed response has reached a steady state. If I simply use the maximum value to represent the steady-state amplitude, it can be misleading—since transient responses prior to reaching steady state may yield a higher peak, as seen in the uploaded code.

2. I do not know how to properly select the steady-state result from the previous frequency as the initial condition for the next frequency step.

The Maple 2024 default Document is largely unreadable to me. the multiplication sign is a minute dot that I miss most of the time on very high resolution monitors.

What really works well for me is Maple Input as was used in Maple 9.5. A Pleasure to work with. Using Maple 2024 it is a real pain to "go figure" all the time.

I tried the Global Config, but there is no way to set the default font and the defualt color so I can get the exact same text and color as Maple 9.5.
After I set the colors to bright red, and change to Monospace 12 font and use mapleinput, all is well.
However there is no way to save this setup as the configuration has no way to set font and color. It does set mapleinput at least.

So how do I fix this GLOBALLY so I dont have to run into Maple2024's microscopic math.

I am trying to create a diagram in Maple using its plotting tools and simulate a simply connected domain and multiple paths between two points.

My first try is the following

I would like to ask if I could create something like that in Maple or should I use another software to draw it?

Dear all
How can I compute the integral from a to b of   y^2 cot(y)

Thank you

I use  Maple 2015 and I try to understand how the simplification rules apply in the case of the expression 

f := n -> (ln(x)^n)^(1/n)

Here n is assumed to be a strictly positive and I consider only the cases "n is an integer" or "1/n is an integer".

All the questions are orange written in the attached file and resumed below:

1. Why simplify(f(2)) simplifies f(2) whereas simplify(f(n)) doesn't simplifies f(n) for any integer n > 2?
    
2. Why simplify(f(1/n)) simplifies f(1/n)?
    
3. Why simplify(f(3)) with adhoc assumptions returns a simplified expression of some form whereas, for any integer n > 3,  simplify(f(n)) with (the same corresponding) adhoc assumptions returns a simplified expression of a complete different form than with n=3?

Can you please have a look to it and give me some clarifications?

When using FunctionAdvisor(branch_cuts, f(x), plot="2D"); how do I enforce discontinuous lines be presented with option discont=true?

To save space, I've decided to show problems found so far in Maple 2025 in one worksheet.

Hoping someone will figure the cause. The big problem is that these internal errors can not be cought using try/catch. Which means there is no user workaround. If they can be cought, then it is not a big problem.

Some from odetest, some from int and some from simplify and some from symgen.

Below is worksheet showing output in Maple 2024.2. It shows NO internal error is generated in any one. Either a result is returned, or it timedout as expected.

This shows all the above cases are regressions in Maple 2025.

This looks like regression in dsolve.

In Maple 2024.2, dsolve solves this with no problem and very quickly. 

In Maple 2025 it just hangs.

Any one could find why this is the case? infolevel does not show why. Below is Maple 2024.2 worksheet and Maple 2025 worksheet.  This is Maple 2024.2 NO HANG

This is Maple 2025. HANGed. Had to terminate it after 15 minutes. It seems to hang on resolving initial conditions.

Given a graph G and a vertex u of G, the problem of determining whether there exists a cycle of length k starting at u is a common one in graph theory.

Mathematica provides a function Findcycle for this task, though I am not sure which algorithm it employs—perhaps depth-first search (DFS)? Maple, on the other hand, does not appear to have a corresponding built-in function.

Hi, why does Maple always automatically distribute coefficients in expressions? For example, if I enter 2*(a + b + c), the result is always 2*a + 2*b + 2*c. Is there a way to keep it as 2*(a + b + c) instead?

Hello everyone,

How I get a plot for this function ? What means numeric values ? 

Thanks !

I am just wondering why something that has been bothering me since Maple V up to including Maple 2024 has never been resolved properly.

Why is it so difficult for maple to solve a dead obvious and simple expression e.g.

sqrt(cos(gamma)^(5/3)/sin(2*gamma)^(5/3));

You can use algsubs to tell maple to use an elementary identity to substitute the double angle away, but even then it refuses to simplify the remaining fraction which is elementary at most.

So, when will e.g. this simple multiple generational issue be addressed  so maple can do the obvious simplifications.

There are much more severe examples concerning trigonometric functions under square roots, which was left out in this case to show just one issue.

How i can get this special parameter i try to do substitution in another mw file but stilli can't reach this parameter and without this parameter my PDE is not give me zero so i have to find this r[i] parameter, some letter of my mw file are not similar to paper but r[i]=l[i] as mention is paper al clear and i found all structure just this remain, i am looking for equation (14), thanks for any help

In the below I would like to format the odes as they appear in the second and third ode (in green brackets).

I.e. making the first operand with the minus sign inside the parentheses the second one. I was hoping for simplify,size but that does not do the trick.

How to do this?

Dear Maple Support Team and Community,

    I would like to report what seems to be a bug in Maple's MatrixExponential function in the LinearAlgebra package.

    Consider the following 8×8 skew-Hermitian matrix B:
 

B := Matrix(8, 8, [[0, I, 0, -I, 0, I, 0, -I], 
                   [-I, 0, I, 0, -I, 0, I, 0], 
                   [0, -I, 0, I, 0, -I, 0, I], 
                   [I, 0, -I, 0, I, 0, -I, 0], 
                   [0, I, 0, -I, 0, I, 0, -I], 
                   [-I, 0, I, 0, -I, 0, I, 0], 
                   [0, -I, 0, I, 0, -I, 0, I], 
                   [I, 0, -I, 0, I, 0, -I, 0]]);

    Now compute the matrix exponential exp(I*t*B) using MatrixExponential

H := LinearAlgebra:-MatrixExponential(I * t * B);

However, this result is inconsistent with the matrix exponential computed using MATLAB and SageMath, both of which give the same result, different from Maple's.

I would appreciate it if someone from the development team could look into this.
