abstract:In calculus an iterated integral is the result of applying integrals to a function of more than one variable (for example f(x,y) or f(x,y,z)) in a way that each of the integrals considers some of the variables as given constants. For example, the function f(x,y), if y is considered a given parameter can be integrated with respect to x, \int f(x,y)dx.
In this paper, somerelationships betweenimproper double integral and improperiterated are discussed, andthecorrespondingresults are generalizedinto the improper triple integrals.
