Determine the analytic function whose real part is 𝑢(𝑥, 𝑦) = sin2𝑥/cosh2𝑦–cos2𝑥

using Direct method

Hey everyone,
I am trying to find the roots of a very large polynomial, specifically targeting the leading Fisher's zero (the root with the smallest positive imaginary part). I'm using Maple's RootFinding[Analytic] package with Digits := 10, but the results only show 5-digit accuracy (see the attached file plz)

1. Why does RootFinding[Analytic] fail to achieve full 10-digit precision despite the Digits setting? Are there hidden limitations or optional parameters to improve this?

2. Are there alternative methods in Maple to accurately locate only the leading zero (without computing all roots in a region)?

In 1D-Math an inert division can be entered as an infix operator using "%/"

The same sequence of chracters does not work the same way in 2D-Math

In 2D-Math I have to use

Is there an infix division operator in 2D-Math?

Is there a helppage describing %arithop and the like?

I was reading a book on complex analysis, and I tried to answer some questions like "Find and plot the sixth roots of unity on Maple."  I tried the following code, which works. Is there any other way to solve and plot the same question?

Hello everyone,

I want to plot some 2D polygon shapes in one plot. Every shape should have their own color. 
for example: from the Plasma colorschem "Plasma 212" 

Can somebody give me an example code ?

Thanks

Hello,

I have several sets of nonlinear equations that need to be solved for certain unknowns. In many cases, the equations admit more than one solution, and Maple is sometimes able to find different solutions by changing the order of the unknowns.

However, in one particular case, I haven't been able to get Maple to find a known solution that was obtained elsewhere.

Below are the equations, the list of unknowns, the solution returned by Maple, and the alternative solution I'm trying to obtain.

Is there a way to guide Maple to find this other solution?

I want to run Maple Linux builds under Windows. I know that this can be done with a virtual machine but that's it.

Are there other options to do that?

I would go for an easy installation with the possibilty to save and load files from the Windows file system and ideally to copy/paste screen content from and to Windows applications.

Any recommendations and/or references?

i did this question before but i didn't get any answer before, but the shape of question is different, the function is different this time i try 3 term like they mention in that paper so there  must be a way for finding R[2],R[1], and R[0]

( squircle is the humoristic name for the 2D open ball of center 0 and radius 1 in L_n norm ).
The equation of the squircle in L_n norm writes  |x|ⁿ+|y|ⁿ = 1

The attached file gives the exact values of the areas of squircles in norms L₂, L₄, L₁₀₀, L₁. 
Unless for n=2 the results are dramatically poor (evalf/Int gives the same wrong results).

The function a(n) gives the exact expression of the squircle area in  L_n norm.

How do I change the legend position so it doesn't cover the plot label?

Before entertaining non-standard solutions to this problem such as building my own from scratch, is the a standard method for changing the position of the default legend generated along with a standard plot? I couldn't find anything about custom legend positions in the help sheets.

I can't help but wonder why this observed behaviour occurs by default? In what kind of plot would I prefer the plot labels to be obscured by the plot legend?

I coppied the Maple.ini file follwing ?worksheet,reference,preferencesfile.

My favorite palette however was not coppied.

How to do this?

I will look for sensitivity analysis for parameters in the epidemic model using the normalization formula, the result should be between -1 to 1 but there are 2 parameters whose values ​​are more than 1, how do I set the limit so that the sensitivity value is between -1 to 1?

How does one create a new section using UI in Maple 2025?

I've done this many times in Maple 2024. To make section there, I simply do
   Insert -> Section

But I am not able to find this using the UI in Maple 2025, under insert 

Ofcourse, I know I can add section using

                    CTRL .

which works. But I was wondering, where is insert section is in the GUI? Hard to find. I do not see anything called section in the menu there., I tried few of the other items, but so far, can't find section.
