Hello, There seems to be a bug in the int() routine when CPV is being used i.e.

restart;
f1 := (int(t^(2*a - 1)/(-t^2 + 1), t = 0 .. infinity, CPV = true) assuming (0 < a, a < 1));

the result given is

f1 := Pi/(2*sin(Pi*a)*(-1)^(1 - a))

but the correct result is

f1 := Pi/2*cot(Pi*a).

Dear everyone, ive been trying to get to learn Maple, and i am using the book: Advanced Problem
Solving Using Maple. 

I am having issues with not getting the same results as the examples. Although i am using the same imput as the examples. So to me that is really odd. I also noted to get the same results as the examples, i had to change the imput to get there. Now this is a bit more complex problem, and i cant figure out where it went wrong. 

Can you help me?

It did seem to produce the answers, however not in the same fashion as the example in the book. I still had to add the values together. No the solution i got is not what i am looking for. 

Greetings,

The Function

This research work demonstrates the use of the MapleSim and Python scientific packages for the correct use of differential equations for engineering students, in the face of the pandemic generated by COVID-19. The main objective is to visualize the teaching and learning process of the subject presented. The methodology used is block diagrams using graphic programming and the one-dimensional symbolic structure. The results are totally optimal since automation was achieved in the differential equations applied to different engineering cases. The applications generated by the scientific software are fully upgradeable and available in the cloud.

hello everyone, i have an idea how to implement adomain decomposition method manually but want to transform the whole method on maple for any kind of non-linear ode.

Respected administration I already posted the same question for the other method, pls do not delete my question

Hello everyone,

I am presently carrying out some computation of which I intend to solve some equations and get the preceeding values. But it would appear that my maple software just keeps showing evaluating without actually producing any results for hours even days. Is this due to my low laptop specs? 

I would love if the community can take a look at the code, and possibly run it to see if it's ok. I have attached the code for reference. 

Thank you.

Hello there, 

While I was trying to calculate the complex (i.e., P and Q) power equations, I got this question. 

Thus, I wonder if I can have a chance to ask the question here:

a. When the voltage and current are defined as functions, taking the t (time) as a input variable, I was not able to get the proper outcome from the operation. Those attempts are labeled as '#1' and '#2' in the attached worksheet. 

b. When the voltage and current are defined as simple complex expression, I was able to see what I wanted. The expression is named as 'ideal' in the attached worksheet. 

c. Therefore, my question is to see if there is a way to make the operaion using the functions in the same way as done by the simple expressions. 

d. Any insight would be appreciated. 

Thank you.
