Objectives
THE AIM OF THE COURSE IS THE deeper LEARNING OF THE BASIC CONCEPTS OF MATHEMATICAL ANALYSIS, CALCULUS and geometry, and of the basic tools of linear algebra, with their physical and engineering applications.
1. KNOWLEDGE AND UNDERSTANDING: THE COURSE IS FINALIZED TO PROVIDE THE STUDENTS WITH a more rich mathematical language a deeper knowledge of the basic mathematical concepts and their representation with particular attention to: matrices and linear systems; vector and euclidean space; eigenvalues and diagonalization; analytic geometry in the space; functions sequences and serie; functions of more variables; differential equations; curves and curvilinear integrals; differential forms and integral on paths; multiple integrals; surfaces and surface integrals.
2. APPLYING KNOWLEDGE AND UNDERSTANDING: THE STUDENT WILL BE ABLE TO FORMULATE MATHEMATICALLY AND TO SOLVE SIMPLE PROBLEMS OF THE APPLIED SCIENCES, EXPECIALLY IN THE CIVIL ENGINEERING FRAMEWORK. IN PARTICULAR, THE STUDENT WILL BE ABLE TO use vector and matrix calculus, tosolve linear systems, compute eigenvalues and eigenvectors, describe analytically and represent geometric figures in the space, establish the convergence of functions sequences and series and compute simple sums, use the differential calculus of more variables, solve problems of maximum and minimum and differential equations, compute the length of a curve and curvilinear integrals of functions and differential forms, multiple integrals, areas and surface integrals.

3. MAKING JUDGEMENTS: THE STUDENT WILL BE ABLE TO CHOOSE THE MOST APPROPRIATE MATHEMATICAL MODEL AND METHOD IN DIFFERENT SITUATIONS, TO ESTABLISH THE PLAUSIBILITY OF A RESULT AND TO CHECK ITS VALIDITY.
4. COMMUNICATION SKILLS: THE STUDENT WILL BE ABLE TO EXPRESS WITH THE SUITABLE TECHNICAL LANGUAGE AND TO REPRESENT GRAPHICALLY THE LEARNED MATHEMATICAL NOTIONS AND TECHNIQUES, AND TO INTEGRATE THEM WITH THOSE ONES OF OTHER SCIENTIFIC DISCIPLINES.
5. LEARNING SKILLS: THE STUDENT WILL GET A MATHEMATICAL BACKGROUND WHICH ALLOWS HIM TO LEARN MORE ADVANCED MATHEMATICAL CONCEPTS AND MORE GENERALLY SCIENTIFIC SUBJECTS WHICH USE MATHEMATICAL TOOLS.

Teaching Methods

THE COURSE CONSISTS OF 48 HOURS OF THEORETIC FRONTAL LECTURES WITH EXAMPLES AND 42 HOURS OF EXCERCISE SESSIONS, IN TOTAL 90 HOURS (9 CREDITS).
THE ATTENDANCE IS MANDATORY. THE STUDENT IS REQUIRED TO ATTEND AT LEAST THE 70% OF THE COURSE, USING HIS PERSONAL BADGE.
Verification of learning
THE EXAM CONSISTS OF TWO PARTS: A WRITTEN TEST WITH THEORETICAL AND NUMERICAL EXERCISES FOR APPLYING KNOWLEDGE; AN ORAL EXAM WITH CONCEPTUAL AND TECHNICAL QUESTIONS CONCERNING THE CONTENTS OF THE COURSE TO VERIFY KNOWLEDGE AND UNDERSTANDING AS WELL AS COMMUNICATION SKILLS.
The final grade, expressed in thirties, is the result of the written and oral assessment.
