Substitution of parts of a PDE...

I'm trying to extract the real and imaginary parts of a given PDE. However, during the substitution step, something unexpected occurs. Specifically, my replacement does not yield the expected result, and an extra term appears: D(k)(t*w + x) in the expression P11. I'm unsure why this term arises and would appreciate any insight into what might be going wrong during the substitution process.

`There is no more prime differentiation variable; all derivatives will be displayed as indexed functions`

declare(u(x, t)); declare(U(xi)); declare(V(xi))

u(x, t)*`will now be displayed as`*u

  

U(xi)*`will now be displayed as`*U

  

V(xi)*`will now be displayed as`*V

Formatting equations for LaTeX output...

salim-barzani 1640 Maple 2024
latex simplification
May 06 2025
1 7

I want to convert my code output into LaTeX format, but the current formatting isn't suitable for presentation. For example, when I use simplify, it sometimes introduces unnecessary fractions, making the expression look cluttered and less elegant on paper. I'm looking for a way to simplify expressions preferably by factoring terms, without introducing extra fractions, so the final LaTeX result appears clean and well-structured.

Combining 2D with 3D visualizations ...

I’ve successfully plotted this exercise, but I’m exploring ways to improve the visualization. Specifically, I’d like to know if it's possible to combine a 2D plot as a smaller inset within a 3D plot, positioned in a corner of the 3D graph.

Additionally, I’ve noticed that although the same data is plotted in different examples, the design and style of the plots can vary significantly, some look much more polished or professional. Are there recommended techniques, functions, or toolboxes in Maple that can help improve the visual design or aesthetic of the plots

Issues with Collecting Terms in Code – ...

ode collect differential-equations

I’m currently trying to collect terms in an expression f^G(xi), but the result is not behaving as expected. I attempted two different coding approaches, but both resulted in errors. This particular case of collecting terms seems to be different from what I’ve encountered before, and I’m unsure how to resolve it.

Could you please advise on how to properly collect the terms in this situation and avoid the errors? Any insight into why this case behaves differently would also be appreciated.

Thank you for your help.
