Important: The student package has been deprecated. Use the superseding command Student[MultivariateCalculus][MultiInt] instead.

This function corresponds to a ``double integral'' of g with respect to x and y. It uses an ``unevaluated'' form of Maple's int function, so only minor simplifications are performed.

For definite integration, a range of integration (x = $a..b$) must be indicated for both variables.

Alternatively you may use a name to indicate a region of integration. This is strictly notational and cannot be evaluated.

Use value to force Doubleint to evaluate like int.

The command with(student,Doubleint) allows the use of the abbreviated form of this command.

$\mathrm{with}\left(\mathrm{student}\right)\:$

$\mathrm{Doubleint}\left(g\left(x\right)\,x\,y\right)$

$\int \left(\int g\left(x\right)\ⅆx\right)\ⅆy$

$\mathrm{Doubleint}\left(hg\,x=1..n\,y=2..4\right)$

${\int }_2^4\left({\int }_1^{n}hg\ⅆx\right)\ⅆy$

$\mathrm{Doubleint}\left(hg\,x\,y\,C\right)$

${\int }_{}^{}\left({\int }_C^{}hg\ⅆx\right)\ⅆy$
