Training objectives
- ------------------------------------------------------------
Modulo: 64317 - ANALISI MATEMATICA A
------------------------------------------------------------
The aim of this course is to present the basic ideas and techniques of differential and integral calculus in one and several variables. We will also try, in spite of the few hours at our disposal, to give to the students something more than a working knowledge of mathematical techniques. Some problems in applied mathmatics will also be discussed and solved. At the end of the course the students must be able to solve problems of maximum and minimum (constrained and unconstrained), compute volumes and areas of surfaces, barycenters of solids and surfaces, compute the flux of a vector fields through a surface (closed or with boundary)

Lectures and exercices on all the subjects of the course. Learning assessment procedures
- The examination consist of a written exam and an oral exam.
The written exam is divided in 2 parts, precisely:
- a first part with 10 questions, where the student is only asked to give the answer, without any justification. In case of a correct answer, the student gets 2 points. On the contrary, he does not get any point, in case of incomplete, incorrect or missing answer.
In this part, the questions concern simple maximum/minimum problems, computation of some integrals, computation of some limits (also with the aid of Taylor formula), study of a series, find and classify the critical points of a function, computation of a simple double integral, find the potential of a conservative field, recognize whether a vector field is conservative or not, computation of the work of vector field through a path.
- a second part, with 2 exercises: here the student is asked to give all the details for the solutions of each exercises. Both exercises worth 7 or 8 points. In this part, typically the exercises concern the study of a function of one variable, the computation of a multiple integral, the study of a regular surface, the computation of the flux of a vector field through a surface (closed or with boundary).
ATTENTION: the second part of the written exam will be checked only in case the student will be able to answer correctly at least 5 out of 10 of the questions in the first part. If this is not the case, the exam is concluded.
Whenever the final evaluation is greater than or equal to 15/30, the student has to pass an oral exam, with 2 theoretical questions on parts of the program. In particular, the 2 questions are taken from the following list:
1) definition of limit (for sequences and functions, of one and several real variables) and definition of continuous function (for functions of one and several real variables)
2) supremum and infimum
3) convergence criteria for sequences and series
4) geometric series and generalized harmonic series (definitions and convergence)
5) theorems of zeros and intermediate values
6) Weierstrass theorem (in one and several real variables)
7) Fermat, Rolle, Lagrange, Cauchy and de L'Hopital Theorems
8) Taylor formula
9) fundamental theorem of calculus
10) integrability criteria for functions of one variable
11) remarkable limits and asymptotics
12 length of a curve and rectifiability of regular curves
13) tangent versor, normal versor and curvature in the plane
14) differentiability for functions of several variables and sufficient conditions for differentiability
15) Hessian matrix and the Schwarz Theorem
16) gradient and directional derivatives
17) level lines of a function and their regularity (implicit function theorem)
18) critical points of a function of several variables and study of their nature by means of the hessian matrix
19) Lagrange multipliers theorem
20) double and triple integrals
21) line and surface integrals
22) conservative vector fields: definition and necessary/sufficient for a vector field to be conservative
23) divergence theorem
At the end of the oral exam, the student will get his final mark: if this is larger than or equal to 18/30, the exam is positively concluded. In case the final mark is less than 18/30, the student will have to pass again the complete exam (i.e. written and oral). Reference texts
