Hi everyone,

I am experiencing what appears to be a problem with Number Formatting in Maple 2026.

I have a worksheet where I calculate a numerical value using evalf, for example:

evalf(1 - (3.7*90)/(10.4*3600))

which returns

0.4663461539

When I select the output and use the Context Panel → Number Format, for example:

• Percent
• 2 decimal places

the preview in the math container changes accordingly (e.g. showing something like 0.45), but the actual numerical output below still displays as

0.4663461539

Changing the number format, decimal places, scientific notation, etc. seems to have no effect on the displayed output.

Even if not using  evalf.

Is this the expected behavior in Maple 2026?

• Does Number Formatting only apply to certain types of expressions or math containers?
• Is there a known issue with formatting numerical output generated by evalf?
• Am I missing a setting that enables formatting of worksheet output?

I have attached a screenshot illustrating the problem.

Any help or clarification would be appreciated.

Thanks!

I would like to calculate a definite integral in the attached file. Doing so numerically is straightforward. However, a symbolic approach initially fails due to three points of discontinuity in the integrand. Yet, these points can be remedied by taking limits. How can the domain in Maple be extended using these limits to achieve continuity across the entire domain?

I would like to solve a differential equation using a series expansion in the attached file for practice purposes. How can the number of terms in the series solution be adjusted? I couldn't find anything about this in the help text.
BTW:
The differential equation is exceptionally tricky for a symbolic solution ;-) .

Dear Maple users

I wanted Maple to draw two planes in 3D with some points on each plane. Each plane are given by an equation of the form a*x+b*y+c*z+d=0. I know there are a number of options.

1. implicitplot3d.

2. Isolate z in the equation in order to plot the plane as the graph of a function of two variables using plot3d.

3. Find two vectors orthogonal to the normal vector and create a plot of a parametrized surface using plot3d.

4. Use the command PlanePlot from the Student:-LinearAlgebra package.

The first option delivers an ugly result due to the grid. It also requires quite a lot of computation internally. The second option can be used, but one need to isolate z in the equation (and what if the plane has the equation z = constant). Option three also is OK, but again require some calculations. The fourth option I just found and it is quite interesting. Unfortunately my points did fall beyond the small square representing the plane, and it seems like there is no way to enlarge this square.

I ended up choosing option 2 and put some transparency on each plane. I am just puzzled why it is so laborious to plot those planes and points. GeoGebra could do it right away. 

Or maybe I have overlooked something?

KInd regards,

Erik

I have a very large system of nonlinear equations in Maple 2025, and the solver takes hours. Any Suggestions?

After starting Maple

I then tried simpler prompts like "Hello", simplify(x),...

For all prompts I get the same error message.
I am not a frequent AI user but this is the first time I see that.
Has anybody else experienced the same?

Can someone send me a prompt that should work?

(Model type was Simple.)

Update:

It seems that this error occurs, when a second instance of Maple 2026.1 is started and AI is consulted in this instance. 

To D(ln@cosh) I have to add an argument to make it work (Edit: no output returned):

D(ln@cosh)(x);
                            sinh(x)
                            -------
                            cosh(x)

According to ?D I expected output according to this

In the attached file, I have solved an ordinary differential equation implicitly. The simplification that is obviously possible using "simplify" is not being performed. Furthermore, "implicitplot" is not working either. I would appreciate some advice.

I have an expression that is an infinite sum with coefficients that are generated recursively (I apologize for previously posting the wrong formula--I corrected it on Aug 28).  I've tried to evaluate it and similar expressions in Maple  but keep getting error messages.  Any suggestions?

I was told this problem is with Maple and the value of StartupWMClass.

Ubuntu 26.04. The maple Icons in the dock appears as the maple icon. When I click to start maple, the running icon appears as a gear. Hovering shows java-lang-Thread.

How do I fix this.

As an exercise to further familiarize myself with Maple, I would like to calculate the definite integral specified in the attached file. The integrand has an antiderivative, and a source lists the value of the integral as approximately 0.57... Based on the plot, this value is plausible according to a simple estimate (Pi/2 * 0.8 / 2). Following standard practice taught in school, I therefore calculated the difference between the values ​​of the antiderivative at the limits of integration. Surprisingly, the result is a complex number. What am I doing wrong? Did the internal Maple calculation switch to complex principal values?

I'm having a strange problem in Maple 2026. When I highlight a fraction to get Maple to display it as a percentage, it leaves the fraction unchanged. Is this a problem that others have encountered as well? And what can be done about it?

1) in Mathcad there is an exponential Threshod for the entire worksheet so that a resulat like 8*10^-10 becomes 0
Is this also possible in Maple Flow 2025 ?
2) is it possible to get rid of the trailing zeros when I choose in the options the dsiplay of number format as 3 decimal digits and 1 minimum exponent digits
Thank you

The uploaded worksheet contains a second order ode with initial conditions which elicits an error message.
How can this error be avoided?

Can the AI Assistant in the Maple 2026 GUI be configured to use Anthropic's Claude Max plans, local AIs (e.g., via LM Studio), or other providers?
