Learning Objectives

The goal of the course is to give students elements and fundamental techniques useful to study sequences and series of functions, calculate limits of functions of several variables, find maximum and minimum of functions, solve some kinds of differential equations, calculate integrals of functions of two or three variables, study the differential forms, calculate the integral of a differential forms.
