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 solve any linear system, to compute integrals and to study function 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.
- Continuous functions: definition, elementary continuous
functions, discontinuity points, theorems on continuous functions:
Weierstrass theorem, theorems on the continuity of the inverse
function and the compound function.
- Differential calculus: definition of first derivative, geometric
meaning, tangent straight line equation to the graph of a
differentiable function, differentiability and continuity relation,
operations with derivatives; De l'Hopital theorem, local and global
extremes, necessary and sufficient conditions for local extremes,
Fermat's theorem, Lagrange theorem, concave and convex functions,
graphs of functions, Taylor polynomial.
Functions of several variables: domain, indifference curves, limits
and continuity, local and global extremes, differential calculus
(partial derivatives, first and second order differential) ,
implicit functions, Taylor formula of the II order, free extremes
computation, cancave and convex functions, constrained extremes
(Lagrange multipliers method).

Teaching methods
Classes on blackboard. Classes in which students are called to
actively participate are scheduled.
Assessment methods
A written test with both exercises and questions. The oral exam is
optional. At the end of the course a test is scheduled.
