MATHEMATICAL ANALYSIS 1
Learning outcomes of the course unit
Knowledge and understanding.
Students must demonstrate knowledge and understanding of the basic results of differential and integral calculus for functions of one real variable.
Applying knowledge and understanding.
Students must be able to apply the forementioned notions to solve medium level problems related to the field of study and to understand how they can be used for solving problems in a more applied context.
Students must be able to evaluate coherence and correctness of results obtained by themselves or by others.
Students must be able to communicate in a clear and precise way mathematical statements in the field of study, also in a context broader than mere calculus.
Students are supposed to be familiar with the basic mathematical tools taught in High School: basic set theory, elementary algebra, logarithms and exponential, trigonometry, equations and inequalities, basic plane analytical geometry.
