Gained competencies  In this course students are introduced to the differential and integral calculus of functions of several variables and vector functions. Primarily the focus is on situations in which the geometric view is possible, i.e. real functions of two or three variables, and functions from R to R2 and R3. During lectures, basic concept is introduced, analyzed, and illustrated by examples. During the exercises students train appropriate techniques to approach to specific problems and for solving them.
