Basic

Knowledge of numerical sets (natural, integer, and rational numbers). Knowledge of power functions with natural, integer, rational exponent, logarithms, absolute value (modulus), square root function. Knowledge of solving methods for equations and polynomial inequalities of degrees one and two, exponential and logarithmic. Familiarity with the use of the sign product rule and the cancellation property to solve more complex equations and inequalities. Knowledge of the basics of analytic geometry: Cartesian coordinate system, equations of lines, parabolas, circumferences, ellipses, and hyperbolas. Knowledge of elementary functions and of their properties. Knowledge of the basis of trigonometry and of the main formulas associated with trigonometric functions.

to the topics presented. The learning material includes a large number of training exercises, that the student has to solve independently. Finally,

every week there are various hours available for clarification meetings with the Professor and with teaching collaborators.

The written part consists of answering questions of a theoretical nature and solving exercises. The written test is not a test to solve the exercises in a mechanical way, but it requires knowing how to correctly and effectively apply the tools of Mathematical Analysis studied during the course, being aware of how the methods are applied in solving some problems. If the result of the written test is greater than 16/30, the student is admitted to the oral test, mainly of a theoretical nature, where the correction of the written test is also discussed.

The student can take the exam by dividing it into two tests related to the program of each of the two semesters of the course.

The course aims to provide a solid basic preparation, to cultivate and develop knowledge and skills in differential and integral calculus for the real valued functions of a real variable, in the theory of limits of functions and sequences, in series. The topics covered are essential to be able to easily face the subsequent courses. The theory is presented with considerable rigor, always starting from ideas and intuition, and at the same time accompanied by numerous examples and exercises, when possible with a concrete meaning.
