the other five normality cases on . It can be generalized in a straightforward way to domains in .

Change of variables

The limits of integration are often not easily interchangeable (without normality or with complex formulae to integrate). One makes a change of variables to rewrite the integral in a more "comfortable" region, which can be described in simpler formulae. To do so, the function must be adapted to the new coordinates.

Example 1a. The function is ; if one adopts the substitution , therefore , one obtains the new function .
