How is a cyclic command sequence programmed?

Alfred_F — Sat, 25 Jul 2026 15:18:20 Z

In the attached file, I would like to calculate the expressions for the function f(n,x) using a recursion for a given index range, e.g., n=3..15. I would appreciate any advice on this.

How to Import Converations from ChatGPT

Responses from the AI assistant in Maple2026 can be copied directly into a Maple Document or Worksheet, Is there a process which allows one to similarly import a external ChatGPT conversation. I have Maple MCP configured in my ChatGPT account.

Dynamic assignment of ranking of variables in DifferentialThomas

Steven_Huang — Sat, 25 Jul 2026 11:56:41 Z

So the problem I encountered is when I try to assign ranking of variables of ODE in ThomasDecomposition, the indexed variables are not allowed. For instance, for an ODE system containing a[0], a[1], a[2] as dependent variables, if I assign:
R := Ranking([x],[a[0],a[1],a[2]])
It throws an error: due to efficiency reasons no variables of type "indexed" are allowed in the list of depended variables NULL;
This is going to be inconvenient when I have to dynamically solve ODE system within a function call, especially when the system is nonlinear and algebraically closed(no integration constants in solutions) and calling DifferentialThomas in dsolve will be slow. I want to know how to resolve this.

How to integrate a trig function with parameter?

Aliocha — Thu, 23 Jul 2026 11:42:49 Z

How to integrate this function (n::posint) :
f := (n, x) -> (1 - cos(n*x))/(1 - cos(x))

Maple is not returning a result. It seems unable to establish the connection with the Dirichlet kernel. Is there a solution that doesn't require forcing a decomposition into a sum of cosinus?

Thank you for your help.

Best regards.

Creation of difference equations

C_R — Thu, 23 Jul 2026 10:44:31 Z

In the context of numerical integration of partial differential equations I am looking for tools to create difference equations for the numerical integration of PDE's. Ideally the desired integration scheme could be given as an input.

The only command that I am aware of is the DiffEquation command from the DynamicSystems package (see ?DynamicSystems,DiffEquation) which is limited to linear time invariant systems and only provides a simple forward integration scheme.

Any insights/examples into the topic of numerical integration of pde's with Maple beyond pdsolve/numeric capabilites is very much appreciated. (I know that Maple comes with advanced numerical solvers for ODE's. MapleSim uses such solvers to integrate systems of ODE's. This seems to be, in terms of computation, close to what I am looking for.)

Is MapleSim and the B&R Connector included in the Student License version of Maple?

sreilly17 — Wed, 22 Jul 2026 12:07:20 Z

Pretty much what the title says. I am a student and I've worked with B&R Automation Studio, which is a SCADA software, with the physical automation components in the lab in college. Now that I'm on the summer break, it would be great to continue this learning via the B&R connector that Maple offer, to create a "digitial twin". However, there doesn't seem to be any information as to whether MapleSim is actually included in the student edition, and whether the connector is included too.

Thanks
