Course content - Calculus and Linear Algebra

Introduction to the course and crash review of preliminary mathematical notions

One-variable functions: basic definitions, graphs and elementary functions (linear, quadratic, polynomial, rational, irrational, power, exponential, logarithmic, absolute value). Odd and even functions. Composite functions. Inverse functions.

Limits and continuity.

Differentiation of one-variable functions: tangents and derivatives, rules of differentiation, chain rule, higher-order derivatives.

Derivatives in use: implicit differentiation and economic examples, differentiation of the inverse function, linear and quadratic approximations, Taylor's formula, elasticities; continuity and differentiability, intermediate-value theorem, De L’Hôpital’s Rule.

Single-variable optimization: local and global extrema, stationary points and first-order condition, simple tests for extreme points, extreme points for concave and convex functions, second-order derivative and convexity, inflection points, study of the graph of a function, asymptotes.

Sequences and series; convergence criteria; geometric series; Taylor's series. Sequences and series in financial mathematics.

Difference equations. Linear, first order, autonomous difference equations. Steady state and convergence analysis. Linear, first order, non autonomous, difference equations. Difference equations in financial mathematics.

Integration: the Riemann integral and its geometrical interpretation; primitives and indefinite integrals, fundamental theorems of integral calculus. Rules and methods of integration: immediate integrals, integration of rational functions, integration by parts, integration by substitution. Improper integrals.

Integration in economics: continuous compounding and discounting, present values.

Differential equations. First order differential equations. Linear, first order, autonomous differential equations. Steady state and convergence analysis. Linear, first order, non-autonomous differential equations. Differential equations with separable variables. Differencial equations in financial mathematics.

Linear algebra: vector spaces, bases and dimension; matrices and their properties, matrix operations, rank and determinant; linear maps and associated matrices, systems of equations, existence of solutions, cases of one solution and infinitely many solutions, Gaussian elimination, inverse of a matrix and Cramer's rule; eigenvalues and eigenvectors.

Multi-variable calculus: partial derivatives with two variables, geometric interpretation; partial elasticities; chain rules, implicit differentiation along a level curve; functions of more variables, gradient, differentials and linear approximations; economic applications.

Multi-variable optimization; maxima, minima and saddle points; tests based on second derivatives; constrained optimization and Lagrange multipliers.

Metodi didattici

Class lectures. During the class lectures (as well as in the additional exercise classes) each topic will be illustrated by examples and worked-out exercises.

Modalità di verifica e valutazione dell'apprendimento

Written exam.

The exam of the first (summer) session can be taken in 3 steps: a first midterm exam (after 1/3 of the course, during the mid-term session of January/February) with a duration 1 hour, a second partial exam (after 2/3 of the course, during the session of April) with a duration of 1 hour on the second part the course, and a third midterm exam of duration 1 hour on the third part of the course during the first call of session of June/July. In occasion of the third partial exam, students who have not taken the partials can only take the total exam (duration 3 hours).

NOTE: ALL CLEF STUDENTS ARE ALLOWED TO TAKE MIDTERM EXAMS AND NOT ONLY FIRST YEAR STUDENTS.

During the exam, students are not allowed to use calculators. Textbooks and other teaching materials are not allowed.

Grade rejection

The only grades that can be rejected without any communication from the student are those of the first mid-term and second mid-term exams.
