Objectives

SPECIFIC AIMS
To introduce fundamental concepts in view of the analyse of functions of several variables. To develop the ability to analyse problems and results and acquire mathematical precision. To induce an educational background for other subjects in the curricula.

Development of the rational capacity of the students and knowledge of essential mathematical concepts. Students should get solid theoretical and practical formation on the main concepts and results of differential and integral calculus of several variables, including the basic theorems of calculus.

DEMONSTRATION OF THE SYLLABUS COHERENCE WITH THE CURRICULAR UNIT'S OBJECTIVES:

This curricular unit introduces fundamental concepts related to the analysis of functions of several variables. It develops the ability to analyze problems and results and acquire mathematical precision. It induces an educational background for other subjects in the subsequent curricular units. The syllabus complements the learning obtained in the curricular unit of Mathematical Analysis 1.

Teaching methods and learning activities

It is essentially a formative subject, coordinating fundamental theoretical knowledge with some approaches which are necessary  in the subjects placed ahead in the course.  At this level it is important to develop intuitive concepts as well as computer skills. The concepts are exposed in a clear and objective way, making frequent use of examples of physical or geometrical nature.

DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:

The focus is on coordination between the fundamental theoretical knowledge and the developments required in the following curricular units, being promoted the intuitive understanding of the concepts and calculation capabilities. It is intended to develop expertise in differential and integral calculus of real and vectorial functions of several variables, being able to apply knowledge and comprehension to solve problems in new situations, in broad multidisciplinar contexts, being able to integrate acquired knowledge.

Evaluation Type

Distributed evaluation without final exam

Assessment Components

Eligibility for exams

Achieving final classification requires compliance with attendance at the course unit, according to the MIEC assessment rules. It is considered that students meet the attendance requirements if, having been regularly enrolled, the number of absences of 25% for each of the classes’ types is not exceeded.

Calculation formula of final grade

Evaluation consists on 2 written assessments (see 1st year calendar). All assessments are compulsory. Not being present in one assessment  implies a grade of "0" in the correspondent grading.

Result of the evaluation at the end of the semester:

CF= final mark
CT1= first written test' mark
CT2= second written test' mark

CF = 0,40*CT1+0,60*CT2

Students that were admited for evaluation at the end of the semester but did not succeed are admited to the exam of appeal.

Observations

Working time estimated out of classes: 4 hours
Due to the covid-19 pandemic crisis and its containing measures the assessment in this second half of the school year 2019/20 will be exclusively by final exam.
