Die von Geogebra ermittelte Stammfunktion ist aber an der Nahtstelle nicht stetig und daher auch nicht differenzierbar. In this case the volume is given by The inner integral corresponds to the cross-sectional area of a slice between y and y+dy. This may be as a consequence either of the shape of the region, or of the complexity of the integrand. When we evaluate iterated integrals, we always work from the inside out. Some textbooks use the notation \(\int_R f(x,y) \, dA\) for a double integral. Consider the case when a three dimensional region \(U\) is a type I region, i.e. on the outside, or vice versa.
