@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

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
