Double integral

["Jordan, Paul" <paul.jordan@roche.com>]

Dear all,

In the help file to the function "integrate", there is the example of a double integral of the form:

   integral(0,5) integral(0,t) f(x) dx dt

Does anyone know a method to caculate a doble integral of the form:

         integral(0,a) integral(0,t) f(x,t) dx dt   (a constant) ?

        Eg. integrand = function(x) x^2 + y^2

Thanks.
