@mmcdara you are totally right, my question is a little bit nonsense, but let me clear my question, my individual system for solving question is complicated and is part part and some time when i can't solve by thus system i have to change my systems and this is one of them which i have to find parameter but really is hard is not easy, Dr.david before 3 month ago he solved some system like that but i think there is somestep extra and we can do more compact i will upload the (2+1)-dimesion which we solved a example like this but this is a little bit different i want come to this topic and solve each kind this type (1,2,3+1)-dimesion and generate a good system for this kind of finding parameter this i hope i made my question clear!

i don't post any i will just post in this account,  and i hope i get my answear my work is now working with maple i am very happy when i get my answear .
!# i think you friend  with  moderator tell them don't delt my question i have a 1000 question but becuase of delete question i don't ask them!

this is another equation which solved before i want apply same for this new equation and other future work

@dharr  i miss your explanation , got it  thank you dear Dr

@mmcdara if in equation i didn't write like that (int(#,x=-infinity..x)) it work for me but why they use this sign of improper integral and don't different from indifinite integral.

@Kitonum  i think this is second time i ask this question but sometime mind is busy thanks so much

@acer thanks...

@mmcdara every thing are set up true but not fast for calculating by my openion is like this we did it for (1+2) dimension  but this is different is for (1+3) dimension i have to find this 

this file is different from the top it is (1+2) dimension

Line-Y-Done.mw

i want find same for (3+1)dimension but i can't what is mistake

Line-Y-Done.mw

@dharr  i did a mistak in there it is becuase of that thank you so much .

@janhardo thanks john

@janhardo  i think you say chatgpt and deppseek but why i can't reach deepseek in pc is like that

also,chatgpt don't give me, is permuim ?

@janhardo i need that Ai which you use relly is a good thing  you do all stuff , tell me or give me a link?

is so nice........................

@janhardo  you did a great job thank you i will try make it easier but for now this is so good i will try to go for three line and in dutch 
Als je het goed vindt, verwijder ik dit bericht over een uur.
Hartelijk dank.

@janhardo this time is worked i can undrestand this code is so better than other, onthing remain, can you do that too? 
at least tell the Ai do that for me change the color of the line both of them are black and take a look see how much is easier

@janhardo watch my file and what i told you use that equation i mentioned

@janhardo your function is wrong in the first when  you use my function without t i told you you have to used and it is used, know i am telling you your function is wrong tell your Ai to use this set up but use my function and line i will upload file
(equ) is shape of of lump and the line is clear is (eq1) and (eq2) is each line have 3 countour which i thing red red must be in eq1 and eq2 be like that set up this it will be done
