Iterated integral
In calculus an iterated integral is the result of applying integrals to a function of more than one variable (for example or
) in a way that each of the integrals considers some of the variables as given constants. For example, the function
, if
is considered a given parameter can be integrated with respect to
,
. The result is a function of
and therefore its integral can be considered. If this is done, the result is the iterated integral
