PRINCIPLES OF MATHEMATICS
Learning outcomes of the course unit
Knowledge and understanding of the basic concepts and tools of calculus and statistics.
Ability to use such tools to study graphs of functions and solve problems related with the study of functions.
Ability to apply such tools to the study of experiments (to create models and/or provide the correct interpretations of the data).

During the lectures we shall describe the basic objects and tools of calculus and statistics,
together with numerous examples and exercise to improve the understanding and to show how to apply them to the resolution of numerical exercises. There will be weekly exercise sessions to recall some basic notions and to provide more examples and exercises.
Assessment methods and criteria
Written exam to check the ability to apply the basic toos of calculus to the solution of concrete numerical exercises.
Oral exam to verify the knowledge and understanding of the basic definitions and theorems of calculus.
