Target skills and knowledge:

The course is a cultural mathematical basis which should be well known by any student who attends a course in any scientific area. The purpose of the course is double. On the one hand, it aims to train the student to adopt some major guidelines for a rigorous analysis of problems and for searching their logic solutions. On the other hand, it is responsible to provide some tools to concretely deal with mathematical problems, also extremely practical ones. For this purpose will be addressed and solved some examples having a physical and/or biological nature. Moreover, the course provides natural prerequisites for the subsequent courses of Statistics, Physics, Chemistry and Genetics. 
Examination methods:

Activities take place in both winter and spring semesters. After each semester there will be written tests 
Assessment criteria:

The acquisition by the student of an intellectual maturity with respect of deductive logic  based methodologies, tools and content taught in class is verified. Next to verification of an understanding of the theoretical content of the course, the student is asked to demonstrate an appropriate capacity in solving new problems formulated in the language of mathematical modeling base. The student must then demonstrate that it is able to: understand the problem, find the correct interpretation by means of mathematical and quantitative methods, develop an appropriate calculation context, understand the answers derived from the method and its inferences . 
Course unit contents:

Elements of mathematical logic. Elementary set theory. Functions acting between sets: graphic of a function; composed functions, injectivity, surjectivity, inverse of a function. Real functions in a real variable. Monotony and invertibility. Inverse of exponential functions, inverse trigonometric functions. Neighbourhoods, accumulation points, limits for functions and their properties. Infinite and infinitesimal functions. Continuous functions and their properties. Derivability of a function. Theorems of Rolle, Lagrange and their applications to the study of monothony of differentiable functions. Theorem of L'Hopital. Higher order derivatives. Study of functions and of their graphic. Search for branches asymptotic. Comparing infinitesimal (resp. Infinite). Order of infinitesimal (resp. Infinite). Approximation of functions, Taylor formula and property of the remainder. Approximate calculation. Indefinite integrals and methods of integration of continuous functions. Definite integral. Theorem of the integral average, theorem of Torricelli and applications to calculus. Study of integral functions. Calculation of planar areas and of volume of solids obtained by revolution.

Additional notes about suggested reading:

In addition to the suggested books, the teachers provide on the web some additional educational materials, such as lecture notes, texts and solutions of assigned tests. In particular, a page of the course is activated in the ELearning platform of the Department of Mathematics, which shows the contents of the lessons carried out and any additional teaching materials, as well as other information related to the course (scheduling and results of the examinations, scheduling meetings and materials relative to teaching support, etc.).
