1. Riemann integral in Rn Review of the Riemann integral in one dimension. Rectanglesin R2, compact support functions, simple functions and their integral, function definition integrable according to Riemann in R2 (hence Rn).

Definition of measurable set, a set is measurable if and only if its boundary has zero measurement. Normal sets with respect to the Cartesian axes. A continuous function on a measurable and integrable set. Fubini reduction theorem.

Formula of change of variable in integrals (without size). Polar, cylindrical, spherical coordinates. Examples: calculation of some barycenters and moments of inertia.

2. Regular curves.

Regular curves in R ^ n. Tangent versor.

Two equivalent curves traveled in the same direction have the same tangent versor.

Length of a curve. It is greater than the displacement.

Two equivalent curves have the same length.

Curvilinear integrals.

3. Surfaces, flows and divergence theorem.

Recalls on the vector product. Definition of regular surface. Tangent plane and normal versor. Area of a surface. Examples: graphs of functions and rotation surfaces. Surface integrals. Flow of a vector field through a surface. Examples. Statement of the divergence theorem. Demonstration of the divergence theorem (for normal domains with respect to the three Cartesian axes.

4. Differential forms and work.

1-Differential forms. Integral of a 1-differential form (work of a vector field), closed and exact forms. A form is exact if and only if the integral on any zero closed curve. Example of incorrect form closed.
