For n > 1, consider a so-called "half-open" n-dimensional hyperrectangular domain T, defined as: Partition each interval [aj, bj) into a finite family Ij of non-overlapping subintervals ijα, with each subinterval closed at the left end, and open at the right end. Then the finite family of subrectangles C given by is a partition of T; that is, the subrectangles Ck are non-overlapping and their union is T. WebAdditive Properties. When integrating a function over two intervals where the upper bound of the first. is the same as the first, the integrands can be combined. Integrands can also be. split into two intervals that hold the same conditions. If the upper and lower bound are the same, the area is 0. If an interval is backwards, the area is the ...
