"Yes, ass...slider142 replied on physicsforums:<br />"Yes, assuming you mean dx dy dz dt. One reason for using d4x instead is to save space, and to not emphasize any particular order for the iterated integrals. (There is also a little matter of the fact that the integral over a region is only equivalent to iterated integration over a series of intervals when the region and function being integrated satisfy certain properties, such as Fubini's theorem, but this is not really a big deal most of the time.)"Georgehttps://www.blogger.com/profile/04824865122846470839noreply@blogger.com
