Learning outcomes
The aim of course is to provide the mathematical tools
needed to study economic and financial models. At the end, students
are required to be able to study functions of real
variables.
Course contents
Real function of a real variable: domain and image, asymptotic
straight lines, elementary functions, compound functions, inverse
function, inverse functions graphs, injective and surjective
functions, relations among injective, monotone and inverse
functions. Limits: function's limit definitions, infinitesimal
order and infinite order, operations with limits. Differential
calculus: definition of first derivative, geometric meaning,
tangent straight line equation to the graph of a differentiable
function operations with derivatives; De l'Hopital theorem, local
and global extremes, necessary and sufficient conditions for local
extremes, Lagrange theorem, , Taylor's polynomial, concave and convex functions,
graphs of functions.
Numerical series: geometric series, harmonic series,
convergence criteria for series with non negative terms and series with alternating sign.

Teaching methods
Classes. For each topic the theoretical results will be presented: for some of them the proof will be provided while for the others only the underlying intuition. Exercises will be solved and examined carefully. Weekly classes taken by the tutor will be devoted to the solution of exercises.
Assessment methods
The assessment method consists in two steps:
1) a preliminary test with 6 questions: each correct answer worth 3
points, each wrong answer -1 point while answers not given are not
considered (their value is 0). A final score of 10 points is
required to be admitted to the second step.
2) a written exam with questions to be solved in details.
The final grade is the weighted average of the achieved
grades.
The final grade of the integrated course of "Matematica" (12
cfu) is the arithmetic mean of the grades obtained in the two
modulus (Matematica Generale and Matematica per l'Economia) if a
grade of at least 14 points is achieved in each exam.
The oral exam is optional but it is required a mean score of at
least 18 points: in case of lower average scores, the admission is at professor's discretion .
