|Course title||Mathematics 3 – Function of several variables|
|Status||Lectures(30), Exercises (30)|
|ECTS||5 ECTS credits|
|Lecturer||Tomislav Marošević, Associate Professor|
|Course objective||The objective of the course is to provide insight into the fundamental parts of mathematics related to functions of several variables: the area of definition, continuity and limes, derivatives and integrals of functions of several variables. Students should be encouraged to think critically and to research.|
|Prerequisites||Mathematics 1, Mathematics 2|

|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.|

|Instructional methods||Lectures and exercises are mandatory.|
|Exam formats||The exam consists of a written and oral part and it is taken after completion of lectures and exercises. During the semester, students can take two or more colloquiums that replace the written examination.|
|Quality control and successfulness follow up||An anonymous questionnaire|
