@mmcdara i invistigate a lot becuase of that i didn't response soon
i solved a lot example and if needed i will upload the target of this finding if mentioned, about this kind finding in begin i was so happy to use this way for finding (x,y,z) but in some example which i get my result by use the old way i try to use yours too but the result is so different why? 
in begin i try for 3-dimesion  which i didn't solved yet but result is a little bit strange becuase of that i try a solved one already
i will upload the mine way and your way and watch the different !

@nm is hard for me to learn how use this notepad++ i will do by classic way...

@dharr  i did but this hapen

K:=null

i try to solved by another way but i have to make all seperate part mw to one worksheet, but a lot time this happen whoch sometime i can't make all of them to one workseet.

@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
