Learning objectives
The aim of the course is to provide a basic knowledge of the following subjects: the general methods of mathematical thinking; elementary set theory; the main number systems and their algebraic and order structures; linear algebra; some elementary functions of one real (or complex) variable; the notion of limit, differential calculus and integral calculus, mainly for real (or complex) functions of one real variable; the use of elementary functions and infinitesimal calculus in some real world applications.
Expected learning outcomes
The student should master the general methods of mathematical reasoning; he/she should attain a deep understanding of the basic theoretical notions provided by the course, and develop the capability to illustrate them in a rational way. In addition, the student should acquire the skill to solve computational problems in the same areas, applying autonomously the solution techniques provided by the course.

Course syllabus
1. Elementary set theory. Basic notions on maps between sets. Relations on sets. Equivalence and order relations. Basics of enumerative combinatorics.
2. The sets N,Z,Q,R of natural numbers, relative integers, rational and real numbers, with their algebraic and order structures. Countability of Q, uncountability of R. Completeness of R. Supremum and infimum of a subset of R. Elementary topological notions in R. The spaces R^n (n=1,2,3, ).
3. A sketch of the abstract notion of vector space. Linear mappings between vector spaces and matrices. Linear equations.
4. Some generalities on real functions from a subset of R to R. Some elementary functions: power functions, exponentials, logarithms, trigonometric functions. Using trigonometric functions in acoustics. An invitation to Fourier series.
5. The notions of limit and continuity for functions from a subset of R to R. Some limits concerning elementary functions. Limits and algebraic operations on functions: indeterminate forms. Limits and composition of functions. Notable special limits. Theorems of Darboux and Weierstrass on continuous functions.
6. Real sequences and their limits. Real series: some examples and convergence criteria.
7. The notion of derivative for a function from a subset of R to R, and its geometrical meaning. An application: the velocity of a particle. Derivatives and algebraic operations on functions. Derivatives of the elementary functions. Derivatives of an inverse function and of the composition of two functions. The theorems of Rolle, Cauchy and Lagrange.
8. Higher order derivatives. An application of the second derivative: the acceleration of a particle. Taylor's formula with reminder in the Peano or in the Lagrange form. Use of Taylor's formula in the calculation of limits, and in the numerical computation of functions. Taylor's series.
9. Using derivatives to determine the maximum and minimum points of a function from a subset of R to R, as well as the intervals where the function is increasing, decreasing, convex or concave. Analyzing other aspects of the graph of such a function; asymptotes.
10. The notion of primitive function, or indefinite integral, for a real function on an interval. Some elementary indefinite integrals. Integration by parts and by substitution in the indefinite case.
11. The notion of Riemann's definite integral for real functions on an interval, and its geometrical meaning. The fundamental theorem of calculus. Integration by parts and by substitution in the definite case. An introduction to improper integrals. Using integrals to estimate finite sums and series.
12. The field C of complex numbers. Modulus, argument and trigonometric representation of a complex number. A sketch of the notions of limit, derivative and integral for complex valued functions. Complex sequences and series. The exponential function in the complex field; Euler's formula. Roots of complex numbers. The fundamental theorem of algebra.
Prerequisites for admission
The course takes place in the initial semester of the first year; consequently, there are no prerequisites except for those required for admission to the degree programme in Music Information Science.
Teaching methods
The course consists of theoretical lectures and exercises sessions. The theoretical lectures will also present, occasionally, the resolution of some exercise. The exercises sessions will be occasionally replaced by the exposition of complementary theoretical subjects.
Further information about the organization of the course will be published on the Ariel web site.
Teaching Resources
THEORETICAL LECTURES. The contents of all lectures about theoretical aspects are exhaustively described by written notes, available on the Ariel web site. These notes also present, occasionally, the resolution of some exercise.
EXERCISES. Some of the contents of the exercises sessions will be described by written notes, to be made available on the Arield web site of the course.
Further material on the resolution of exercises is available
on the Ariel sites ''Minimat'' and ''Matematica assistita'' .
FURTHER REFERENCES. The material mentioned before is more than
enough to prepare exams. Just for completeness, some classical textbooks on the topics of the course are listed hereafter.

Assessment methods and Criteria
The examination consists of a written and an oral exam.
During the written exam the student must solve some computational problems, formulated as open-ended questions.
Each written exam receives a numerical rating in the range 0-30; this rating is communicated to the student immediately after the correction (typically, few days after the date of the exam).
The oral exam can be taken only if the written component has received a rating not lower than 15.
During the oral exam the student is demanded to show that he/she masters the main theoretical concepts illustrated in the course, including the proofs of the main theorems, and that he/she is able to expose them rationally. Again during the oral exam, at the discretion of the examiners, the student can be invited to
discuss his/her written exam and, possibly, to solve a computational problem similar to one that he/she has not managed adequately during the written exam.
The complete final exam is passed if both the written and oral parts are passed.
Final marks are given using the numerical range 0-30, and taking into account both the written and the oral parts. These final marks are communicated immediately after the oral exam.
For further information about examinations, see the Ariel web site of the course; this reports the texts of all problems assigned for written exams during the last years, and also makes available a guide to the preparation of the oral exam.
