Imagine that the following summation needs to be constructed to create a graph. Suppose the text below provides us with this relationship between the equations

The table below further provides us with such relationships.

If we assume that the unprovided constants are equal to 1, then what does a graph look like for the remaining variables?

I have difficulty implementing a system containing sums

Some of the calculations mentioned here can be done in alternative programming languages, such as Python, C, and so on. However, I would like to reproduce exactly these graphs using Maple (without the need for programming commands, such as "if", "while", among others).

In the work I am trying to reproduce, we have "The evaluation of the influence of the inclusion of the broadband behavior of grounding systems in EMT-type programs in the evaluation of transients resulting from direct lightning strikes on transmission lines. The behavior of the grounding frequency is determined using an accurate electromagnetic model and included in the EMTP/ATP by means of an equivalent circuit derived from the Vector Fitting technique. In addition, the impact of the frequency dependence of soil parameters on the lightning performance of transmission lines is addressed." This may seem somewhat disconnected from reality for many, since it is a problem involving electrical engineering optimization.

Could someone help me reproduce these calculations? I have made little significant progress.

Suppose I want to run several systems of equations as below, however, the processing time exceeds 45 thousand seconds (reaching hours of calculations)

  • What is better, buying a new processor (new notebook) or buying a new stick of RAM?
  • Or does none of this affect Maple? Therefore, it is just a computational disadvantage (the delay time), characterizing the slowness of the program for very large systems as an imminent characteristic.
  • Another question: The newer Maples (new versions) seem to be heavier to run. Is it just me? What seems to me is that the previous versions of Maple, because they contain fewer resources, are lighter and run certain calculations faster. Would this be correct?
  • Last question: Is it possible to do parallel processing in Maple? So that calculations on huge systems can be run faster

Thank you so much! :)

Given a graph, as in the example below, I need all of them to have the same size, for example, 7 cm horizontally and 4 cm vertically. Is there a command to standardize the entire graph?

I have to follow certain dimensions that Maple usually does not show when adjusting the graph size with the mouse.

with(plots);

NMC := [0, ln(2)], [6, ln(2)];
plot([NMC], color = black);

Thank you so much!

I need to automatically solve this system, that is, both equations simultaneously for different intervals of T that I define. For example, from T=0.1 to 4, then from 4.5 to 5 and from 7 to 8 with distinct subdivisions between them, the first varying by 0.1, the second by 0.05 and the third by 0.25. Furthermore, the index that accompanies m and G is only illustrative. Would anyone know how to help me?

Thank you for your help!
