Mathematics: the required prerequisites for enrollment in the School of Engineering.

The course is aimed at providing the basic knowledge of calculus (differential, integral) for real and vector-valued functions of one or several real variables, together with the fundamentals of the theory of series and with an introduction to ordinary differential equations. Lectures will be mainly focused on the comprehension of notions (definitions, results), although some proofs will still be detailed. Examples and exercises will be presented. By the end of the course the Students are expected to be able to handle correctly and without hesitation limits, derivatives, function graphs, integrals (also multiple, line and surface integrals), series, linear differential equations, and the corresponding theoretical facts.

Functions, Limits, Continuity.
