Inquadramento dell'insegnamento nel percorso del corso di studio
This is the first of the two parts of a compulsory first year course in Mathematics. It aims at providing all fundamental tools in Calculus and Linear Algebra used in economic and managerial disciplines, along with examples and models of economic vocation.
In "Mathematics I" a particular attention is paid to problems of maximization and minimization of functions of one variable, as preparatory to optimization in multiple variables (discussed in the second part of the course).
Risultati di apprendimento attesi
At the end of “Mathematics I” students should have acquired the fundamentals of calculus in one variable. Specifically, students should have acquired the following skills.
a) Knowledge and understanding
a.1) Knowledge of basic definitions in calculus in one variable, such as: derivatives, limits, integrals;
a.2) Interpretation of the above definitions in terms of geometric properties, supported by a span of crucial examples.
b) Ability to apply knowledge and understanding
b.1) Ability to compute, for functions of one variable: derivatives, limits, integrals (elementary, by parts, by substitution);
b.2) Ability to analyse properties of functions of one variable, such as monotonicity, convexity, behaviour in the long run;
b.3) Ability to compute stationary and inflection points; ability to maximize/minimize a quantity described by a one variable function, particularly when it describes an economic variable;
b.3) Ability to interpret all above properties in examples of economic/managerial vocation.
c) (Lifelong) learning skills
c.1) Improved ability to handle a formal language, to make logic deductions; enhance rigorous rational thinking;
c.2) Improved ability to translate a problem into formal terms, solve it and interpret the solution in terms of the original problem.
Prerequisiti
Students must be clear of didactic debts (Additional Learning Requirements, ALR).
Topics usually taught at school of upper secondary education are given as known. In particular: the basics of set theory, real numbers; algebraic operations and properties of real numbers; powers and fractional powers, absolute values; equations and inequalities of first/second order, rational, irrational, exponential and logarithmic type; linear and quadratic functions; exponential and logarithmic functions; elements of analytic geometry: cartesian coordinates, distance of points in the plane, lines, parabolas, ellipses, hyperbolas and their equations and graphs in the plane.

In addition, lecture slides, homework and solved exams are made available on the webpage of the course, the university e-learning platform moodle.unive.it.
Modalità di verifica dell'apprendimento
Grading is based on a final written exam, including all topics taught in Mathematics I and Mathematics II, and an optional oral exam.
The exam consists of 6 problems, 3 of which on the topics Mathematics I, and 3 on those of Mathematics II, to be solved in 2h30’ overall. Abilities acquired by students are verified by requiring them to solve the problems. Their acquired knowledge is verified by asking them to justify in detail their answers, on the basis of the theoretical results (definitions and theorems) presented and practised in class during the course.
The exam is closed-notes and closed-book, but students are allowed to use a pocket calculator (scientific calculators computing derivatives and integrals, or plotting graphs, are not allowed).
Students scoring 18/30 or above may register the grade or ask for the optional oral exam. With the oral exam the grade may be raised or diminished. Students scoring between 16/30 and 18/30 also may ask for the optional oral exam, and register grades reaching a minimum of 18/30 (after the orals).
Two partial exams are issued during the course time span, one covering the topics of Mathematics I and one covering those of Mathematics II. A score in each of the partial equal or above 8/30 is considered equivalent to the final written exam, with overall grade equal to the sum of the grades of the partials. (The rules for orals apply similarly).
Metodi didattici
The topics of the course are conveyed by means of face-to-face lectures and practise sessions, and weekly office hours after class.
In particular, during the course time, office hours are held in public. Students may come and ask questions or simply sit and listen to other students’ questions and to the instructor’s answers. A further discussion is also possible on appointment.
The topics discussed in class are supported by materials made available for download on the webpage of the course, including:
a) the complete set of slides/lecture notes;
b) weekly sets of homework exercises;
c) a list of previous exams, all completely solved
d) all relevant information about the course, and real time updates.
