I was investigating a bug and repeatedly opened worksheets. In one of the former worksheets I used the debugger and closed it. In the below case there was no debugger running in the worksheet and also no debugger was visible as a separate Windows task in the task bar.

In this case below the message from the debugger is displayed delayed (i.e. when a new statement is entered).

For comparision: No delay with Maple 2025 screen reader

Could it be that the new GUI mixes up mservers?

Is the above reproducible?

Good day.

I am constructing a 4-set Venn Diagram and I would like to know if it is possible to fix the number of decimal places in the solution.

The attached worksheet is given as an example; the default number of decimal places seems to be 2. I would like this to be either 0 or 1 (for both absolute and relative values). 

Does anyone know how to do this? 

Thanks for reading!

In the attached file, I'm trying to calculate a limit. After a long calculation, I've given up. I'm asking for advice on how to perform the calculation effectively in Maple. I know the solution using the pen and paper method (pi/4+1/2*ln(2)).

This below shows strange side effect of calling latex(sol,'output'='string'):

Code reads two different strings that represents two maple command. (they in database in actual application)

The commands are parsed and evaluated giving solutions OK.

But if the first solution is converted to Latex before processing the second string,  then the parsing of the second fails. 

If Latex is not called in between, then no problem happen parsing the second command and it gives solution ok.

Any idea why this happens and any workaround so code can call latex in between without getting this error?

i.e.   run_it(p1); run_it(p2);  WORKS

But   run_it(p1); latex(sol,output=string);  run_it(p2);  FAIL

Clearly there is some global/buffering issue somewhere.

This simple expression (from a recent post) crashes Maple:

simplify(tan(Pi/5) + sin(Pi/15) - sqrt(15));

In Maple 2025, in a new worksheet, this command crashes Maple; it is not possible to interrupt the computation (with the "Stop" button) and the worksheet must be closed.
In Maple 2024, the computation can be interrupted, but after repeating (maybe twice) the command, the interruption becomes impossible.

Question: is there a simpler command which crashes Maple?

Hey guys, 

I am solving big systems of equations and doing some other stuff with the results. So now I got two diffrent ways and it turns out, that the give back the same result but they present it in diffrent ways. So my quesion now is, how can I simplify a symbolic number to its shortest form. In my example you can see, that the diffrence of y_1 and y_2 is 0, so they describe the same number. However y_2 is a way more complicated expression. So here I know the easier expression, but what if I dont. What is the right command to force maple to find a simplier expression for y_2? I read about evala but its doent do the job as you can see in the attached file. I also tryd things like simplify, normal, expand but it didint worked out too. simplify_symbolic_numbers.mw

Thank you for your help.

Some menu fonts have become smaller under Windows 10 for some reason.
There where no changes of the system settings nor system updates. A system restart did not restore to normal font size. This also on Maple 2024 and lower.

Any ideas what could have caused this and how to restore to normal?

That's from annother Windows 10 system.

I recently solved the following Diophantine equations:
tan(3*pi/x)+4*sin(2*pi/x)-sqrt(x)=0
and
tan(13*pi/x)+4*sin(19*pi/x)-sqrt(x)=0
Unlike my old "pencil and paper" solution, I used Maple to practice with some sub-calculations to get some guesses for the solution. To confirm my guesses, I inserted them into the equations and used "simplify." The result was "zero." Is this "zero" the mathematically exact zero, or does Maple display a very small real number as "zero" after applying "simplify"?

I am working on obtaining the complete set of solutions for a given ordinary differential equation (ODE). While testing various cases from the auxiliary ODE method, I derived a solution of the form U(ξ). However, I am currently unable to determine which specific case or class from the established solution set this result corresponds to.

I would appreciate any guidance or method to correctly classify each obtained solution U(ξ) according to its respective case within the set of auxiliary ODE cases.

 Hi,

How can I replace all the expressions diff(G(xi), xi)/G(xi) with the new variable w(xi) in the next step? (Even the ones that have powers)

How to solve these pde equations in maple to get the similar type graphs.

Ode equations we can solve directly but these equations are pde .

in the article they have solved the governing equations by series solution? 

can we solve these equations in maple also by series solution or any other method is there to solve these equations

I have used plot3d in Maple to generate a 3D plot, but I’m not sure how to export it in high resolution. I tried right-clicking to export the image directly, but the SVG output appeared garbled, and the JPEG version was too low in quality. I also attempted to export the plot using commands, but the resulting image still lacked sufficient resolution. I would like to ask how I can properly export a high-quality 3D figure from Maple.

Commands I have tried：

plotsetup(jpeg, plotoutput = "C:/Users/gfy/Desktop/data5151.jpg", plotoptions = `dpi=1200`);
print(ddd);
plotsetup(default);

How to replace the symbols “true” with t and “false” with f in the output of the following code:

with(Logic);

TruthTable(a &xor b)

I tried the following but it didn't work.
subs([true = t, false = f], TruthTable(a &xor b));

This solution by dsolve is correct. I get same solution. The problem is odetest does not give zero.

All my simplification attempts failed and adding assumptions to call to odetest does not change anything for what I tried. i.e. could not make Maple show that the result of odetest is zero.

Any one can come up with smart way to verify this solution is correct?

Note that coulditbe(the_residue=0) gives true, but this is not reliable way to check, so this method does not coumt.

I created the next code:

f := M+2*e*sin(M)+(5/4)*e^2*sin(2*M)+(13/12)*e^3*sin(3*M)-(1/4)*e^3*sin(M)+e^4*((103/96)*sin(4*M)-(11/24)*sin(2*M))

fb := Mb+2*eb*sin(Mb)+(5/4)*eb^2*sin(2*Mb)+(13/12)*eb^3*sin(3*Mb)-(1/4)*eb^3*sin(Mb)+eb^4*((103/96)*sin(4*Mb)-(11/24)*sin(2*Mb))

x := cos(wb-w+fb-f)

rho1 := ab*(1-eb^2)/(1+eb*cos(fb))

rho2 := a*(1-e^2)/(1+e*cos(f))

P3 = (5/2)*x^3-(3/2)*x

R3 = GM3*(rho1/rho2)^3*P3/rho2

When I do 

R3exp := mtaylor(R3, [e, eb], 5);

it returns 

R3exp := R3

When I do 

> R3temp := series(R3, e = 0, 5);
> R3exp := series(R3temp, eb = 0, 5);
> convert(R3exp, polynom);

it returns

R3

Could you tell me how I can expand in Taylor R3 around e=0 and eb=0 ?
